Tesla Autopilot

Suite of advanced driver-assistance system features

Image credit is listed at the end of this article.

Tesla Autopilot/FSD is an advanced driver-assistance system (ADAS) developed by Tesla, Inc. that provides partial vehicle automation, corresponding to Level 2 automation as defined by SAE International. All Tesla vehicles produced after April 2019 include Autopilot, which provides autosteer and traffic-aware cruise control. As of February 2026, customers can subscribe to an optional Level 2 package called "Full Self-Driving (Supervised)" (FSD), which adds semi-autonomous navigation on nearly all roads, self-parking, and the ability to summon the car from a parking space. In May 2026, the National Highway Traffic Safety Administration (NHTSA) said that recent Tesla Model Ys are the first cars to pass the agency’s new benchmark for advanced driver assistance systems.

Since 2013, Tesla CEO Elon Musk has repeatedly predicted that the company would achieve fully autonomous driving (SAE Level 5) within one to three years, but as of July 2026, these goals are still to be met. The branding of Full Self-Driving has drawn criticism for potentially misleading consumers. Tesla vehicles currently require continuous driver supervision which does not constitute full self-driving capability. Previously, the Autopilot branding was criticized for similar reasons, despite the fact that no autopilot system in aircraft rendered them fully autonomous.

Tesla states that its driver-assistance features improve safety and reduce accidents caused by driver fatigue or inattention. However, collisions and fatalities involving Autopilot and FSD have attracted scrutiny from media and regulators. Industry experts and safety advocates have raised concerns about the deployment of the software to the general public, calling the practice risky and potentially irresponsible.

01History

Elon Musk first discussed the Tesla Autopilot system publicly in 2013, noting that "Autopilot is a good thing to have in planes, and we should have it in cars." At the time, no autopilot system in aircraft rendered them fully autonomous. Over the ensuing decade, Autopilot went through a series of hardware and software enhancements, gradually approaching the goal of full autonomy, which, as of April 2026, remains unmet. Autopilot, as initially introduced in 2014, referred to automatic parking and low-speed summoning on private property, using sensor and computing hardware developed by Mobileye. By 2016, the Mobileye-based Autopilot had added automatic emergency braking (AEB), adaptive cruise control (ACC), and lane centering capabilities, but Tesla and Mobileye dissolved their partnership that July.

Enhanced Autopilot (EAP) was announced in late 2016 as an extra-cost option that used a new hardware suite developed by Tesla. The release of the key EAP feature "Navigate on Autopilot", which uses the new hardware suite to guide the vehicle on controlled-access roads, from on-ramp to off-ramp, was delayed until 2018.

When EAP was announced in 2016, Tesla also offered for purchase Full Self-Driving (FSD) as an upgrade option to EAP, which extended machine-guided driving capabilities to local roads. When the "Paint it Black" video demonstrating FSD was released in 2016, actual FSD was acknowledged to be "some way off in the future." The option to purchase the FSD upgrade to EAP was removed from Tesla's website in October 2018; Elon Musk tweeted the upgrade was "causing too much confusion". Technology analyst Rob Enderle called the removal of the upgrade option "incredibly stupid", adding "don't release a system that doesn't work and make it hard to order." During a January 2019 earnings call, Elon Musk reiterated "full self-driving capability is there", referring to "Navigate on Autopilot", an EAP feature limited to controlled-access highways. The EAP option was replaced by FSD in 2019 without offering "Navigate on Autopilot"-like functionality for local roads; autosteer and traffic-aware cruise control were transferred to the basic Autopilot feature set, which was made standard on all new Teslas.

In September 2020, Tesla reintroduced the term Enhanced Autopilot to distinguish the existing subset of features which included high-speed highway travel and low-speed parking and summoning, from FSD, which would add medium-speed city road travel. Tesla released a "beta" version of its FSD software (which extended "Navigate on Autopilot"-like machine-controlled driving and navigation to 'local roads') in the United States in October 2020 to EAP testers. The EAP option tier was made available to all buyers by June 2022 and the FSD beta had expanded to 160,000 testers in the United States and Canada by September. In November 2022, the FSD beta was extended to all owners in North America who had purchased the option. In April 2024, EAP was removed from the North American design pages, although it is still available for purchase in other markets.

02Hardware iterations

Hardware 1 and Autopilot (Mobileye)

In October 2014, Tesla offered customers the ability to pre-purchase Autopilot that was not designed for self-driving. Initial versions were built in partnership with Mobileye, but Mobileye ended the partnership in July 2016 because Tesla "was pushing the envelope in terms of safety".

Vehicles manufactured after September 2014 included Hardware 1 (HW1), which supported Autopilot. The first Autopilot software release came in October 2015 as part of Tesla software version 7.0. Version 7.1 removed some features to discourage risky driving.

Version 8.0 processed radar signals to create a point cloud similar to lidar to help navigate in low visibility. In November 2016, Autopilot 8.0 was updated to encourage drivers to grip the steering wheel. By November 2016, Autopilot had operated for 300 million miles (480 million km).

Hardware 2

In October 2016, Autopilot sensors and computing hardware transitioned to Hardware 2 (HW2) for new cars, the upgraded hardware collectively was called Autopilot 2.0 to distinguish it from the original Autopilot/HW1 vehicles. At the time it was launched, Autopilot 2.0 vehicles with HW2 actually had fewer features than HW1 vehicles; for example, HW2 vehicles were unable to be summoned in 2016.

Tesla also used the term Enhanced Autopilot (EAP) to refer to planned capabilities that would be coming to HW2 vehicles - the signature EAP feature announced in December 2016 was "Navigate on Autopilot", which allows machine-controlled driving on controlled-access highways from on-ramp to off-ramp, including the abilities to change lanes without driver input, transition from one freeway to another, and exit. HW2 vehicles were updated in January and February 2017 with software version 8.0, which included Traffic-Aware Cruise Control and Autosteer (lane-centering) on divided highways and 'local roads' up to speeds of 45 miles per hour (72 km/h). Version 8.0 also put more emphasis on the radar system, in an attempt to try to avoid problems like the fatal 2016 Autopilot crash in Florida. Software version 8.1 for HW2 arrived in March 2017, providing HW2 cars features on par with HW1 cars, but did not include "Navigate on Autopilot".

In August 2017, Tesla announced Hardware 2.5 (HW2.5), which upgraded the on-board processor and added redundant systems. Software version 9.0 was released in October 2018 in preparation for the release of "Navigate on Autopilot" for HW2/HW2.5 vehicles with EAP, which was implemented later that month. Simultaneously, Tesla removed the option to purchase the "Full Self-Driving" upgrade. In a November 2018 test drive, The Verge reporter Andrew J. Hawkins called the beta of Navigate on Autopilot "the feature that could give Tesla an edge as it grows from niche company to global powerhouse". As initially released, Navigate on Autopilot would suggest lane changes, but could not change lanes until the suggestion had been confirmed by the driver through the turn signal stalk.

Hardware 3

In March 2019, Tesla transitioned to Hardware 3 (HW3) for new cars. Completely automated lane changes without requiring driver confirmation using "Navigate on Autopilot" were added as an option in an April software update, although Consumer Reports called it "far less competent" than a human driver. To comply with the new United Nations Economic Commission for Europe regulation related to automatically commanded steering function, Tesla provided an updated Autopilot in May, limited to Europe. In September, Tesla released software version 10 to Early Access Program testers, citing improvements in driving visualization and automatic lane changes.

In 2021, Tesla began transitioning from using radar to only using Tesla Vision. In October 2022 it provided its reasoning, citing "safety." Vehicles manufactured after 2022 do not include radar or ultrasonic sensors.

In April 2026, Musk stated that, contrary to previous company promises, HW3 cars do not have the capability for unsupervised full-self-driving. Musk said Tesla will offer hardware upgrades to HW3 cars to bring them up to HW4, without specifying a timeframe. Tesla executives have previously said that the company would wait until development of FSD stabilized. Musk said HW3 owners would also be offered to trade-up to a newer car at a discount, but didn’t say whether the company would let lifetime FSD owners transfer their access to the new car.

Hardware 4

Samsung makes the processor for Hardware 4 (HW4) on a 7 nm process. The custom System on a chip (SoC) is called "FSD Computer 2". The board has 16 GB of RAM and 256 GB of storage, which are two and four times the RAM and storage in HW3 respectively. Musk stated that HW4 computational capabilities are three to eight times more powerful than HW3. A tear down of a HW4 Model S and Model X car in 2023 revealed that they have high definition radar hardware, but the software did not use radar.

Tesla started shipping cars with HW4 in January 2023, starting with the refreshed Model S and Model Y, but without FSD; it took six months before HW4-based cars ran FSD. Despite the increased image sensor resolution with HW4-equipped cars, HW4 initially ran the FSD software by emulating HW3, including downsizing the camera images - a result of Tesla postponing training based on the new HW4 cameras. By FSD v13 in late 2024, Tesla was using full-resolution AI4 inputs and native AI4 neural-network architectures.

Hardware 4 plus (AI4.1 or AI4+)

At the Tesla Q1 earnings call on April 22, 2026, Elon Musk announced that HW4 will be receiving an upgrade named AI4.1, with newer-generation memory chips, the memory size going from 16GB to 32GB per chip (64GB total for the two chips in the configuration), and a 10% increase in computing power and memory bandwidth. HW4 plus (AI4.1 or AI4+) was scheduled to begin production in 2027.

In July 2026, increased memory in the Tesla Cybercab FSD hardware configuration was reported. In September 2026, the Cybercab was reported to have "similar autopilot computer to HW4 with some iterative updates".

Hardware 5 (AI5)

Musk announced Hardware 5 (HW5), renamed AI5, during the Tesla annual meeting in June 2024. He said it was scheduled for release in January 2026, but in that month the schedule was revised to early 2027. He said it would be ten times more powerful than HW4 and use up to 800 watts when processing complex environments, versus a maximum of 300 watts for HW3 and HW4.

In January 2026, Musk said "AI4 by itself will achieve self-driving safety levels very far above human. AI5 will make the cars almost perfect and greatly enhance Optimus [robots]", but in April 2026, he said that AI5 will not be used for cars and will be used for "Optimus and [Tesla's] supercomputer clusters. AI4 is enough to achieve much better than human safety for FSD."

03Autopilot packages

Autopilot

Autopilot is the basic package that comes included on the Models S, 3, X, and Y. Autopilot features adaptive cruise control (named Traffic-Aware Cruise Control or TACC) and lane centering (Autosteer). The package also includes minor features such as "green light chime" and standard safety systems such as automatic emergency braking, lane and roadway edge departure warning and correction, and blind spot indicators.

The Cybertruck and standard variants of Models 3/Y do not include Autosteer. In January 2026, Tesla announced that new vehicles sold would not include Autosteer.

Enhanced Autopilot (EAP)

Enhanced Autopilot is a middle ground package, offering Summon, Auto Lane Change, Navigate on Autopilot, and Autopark. Vehicles that support EAP are the Models S, 3, X, and Y. North American customers are currently unable to purchase this package, although it remains active on cars for which it was purchased.

Navigate on Autopilot

Navigate on Autopilot allows the vehicle to maneuver on the highway from on ramp to off ramp, making lane changes and navigating interchanges as needed - similar to FSD. Upon exiting the highway, the vehicle notifies the driver and returns to the basic Autosteer.

Summon

Summon is separated into three categories: Dumb Summon, Smart Summon, and Actual Smart Summon. It can be activated through the Tesla mobile app or the key fob. Dumb Summon is used to move the vehicle forwards or backwards. Smart Summon, now deprecated, drives the car to either the user or a designated location, relying on the vehicle's ultrasonic sensors (USS) to navigate and avoid collisions. Actual Smart Summon (ASS) performs the same job as its predecessor, however it uses the onboard cameras instead of USS. Actual Smart Summon can only be used through the app and features a larger summon radius compared to Smart Summon.

Within the user interface on the Tesla app, ASS displays the vehicle's cameras during summoning while the previous iteration does not.

Autopark

Autopark is capable of parking the vehicle for the driver. Users are given the option to use Autopark when the vehicle detects an empty parking space, and Autopark maneuvers the vehicles into the parking spot. At first, to activate the system, drivers were required to slowly drive past an empty spot until the system detected the space. In 2024, Tesla released a redesigned Autopark, which uses the vehicle's cameras and introduced a "tap-to-park" system. Users are shown all possible parking spots and are able to choose a specific spot. Autopark currently is only able to back into spaces.

Full Self-Driving (FSD)

Full Self-Driving is the top end of the packages, featuring traffic light and stop sign recognition and "Autosteer on City Streets". Visualizations displayed on the vehicle's screen are more detailed and the vehicle is able to navigate local roads, similar to Navigate on Autopilot. As of April 2026, FSD is available in North America for all current Tesla models, including the Cybertruck.

Pricing

In 2015, Autopilot was US$2,500 on a Model S. In 2016, Enhanced Autopilot (EAP) was $5,000, and FSD was an add-on for $3,000. In April 2019, basic Autopilot was included in every Tesla car, and FSD was $5,000, growing to $10,000 in October 2020 and $15,000 in September 2022. As the price of FSD increased, the fraction of buyers who purchased it steadily declined, from an estimated 37% in 2019 to 22% in 2020 to 12% in 2021.

Starting in 2021, the company offered a subscription for FSD for $199 per month or $99 per month if the customer had already purchased EAP. In September 2023, the price of FSD was reduced to $12,000. In April 2024 with the removal of EAP, Tesla reduced the FSD subscription price to $99 per month for either new users or users who had already purchased EAP, and reduced the purchase price of FSD to $8,000. The reduction ran opposite Musk's earlier statements about how the price of FSD would continue to increase, and angered existing FSD users who paid the higher prices.

In February 2026, Tesla ended the sale of FSD to consumers, leaving subscribing as the only option. Musk also stated that as FSD becomes more capable, the subscription price will increase. For EAP owners, the subscription price was reduced to $49 per month.

04Full Self-Driving capability

Approach

Tesla's approach to achieving SAE Level 5 is to train a neural network using the behavior of 6+ million Tesla drivers using chiefly visible light cameras and the coarse-grained two-dimensional maps used for navigation. Tesla has made a deliberate decision to not use lidar, which Elon Musk has called "stupid, expensive and unnecessary". This makes Tesla's approach markedly different from that of other companies like Waymo which trains its neural network using the behavior of a small number of highly trained drivers, and is additionally relying on highly detailed (centimeter-scale) three-dimensional maps and lidar in its autonomous vehicles.

According to Elon Musk, full autonomy is "really a software limitation: The hardware exists to create full autonomy, so it's really about developing advanced, narrow AI for the car to operate on." The Autopilot development focus is on "increasingly sophisticated neural nets that can operate in reasonably sized computers in the car". According to Musk, "the car will learn over time", including from other cars.

Tesla's software has been trained based on 10 billion miles (16 billion km) driven by Tesla vehicles on public roads, as of May 2026. Alongside hundreds of millions of miles on public roads, competitors have trained their software on tens of billions of miles in computer simulations. In terms of computing hardware, Tesla designed a self-driving computer chip that has been installed in its cars since March 2019 and also designed and built in-house a neural network training supercomputer ("Tesla Dojo"); other vehicle automation companies such as Waymo regularly use custom chipsets and neural networks as well.

Predictions

I don't think we have to worry about autonomous cars because it's a sort of a narrow form of AI. It's not something I think is very difficult. To do autonomous driving that is to a degree much safer than a person, is much easier than people think. [...] I almost view it like a solved problem.

, Elon Musk, Opening keynote, Nvidia conference (March 2015)

In December 2015, Musk predicted that "complete autonomy" would be implemented by 2018. At the end of 2016, Tesla expected to demonstrate full autonomy by the end of 2017, and in April 2017, Musk predicted that in around two years, drivers would be able to sleep in their vehicle while it drives itself. In 2018 Tesla revised the date to demonstrate full autonomy to be by the end of 2019.

I think we will be feature complete, full self-driving, this year. Meaning the car will be able to find you in a parking lot, pick you up and take you all the way to your destination without an intervention. This year. I would say I am of certain of that, that is not a question mark. However, people sometimes will extrapolate that to mean now it works with 100% certainty, requiring no observation, perfectly, this is not the case.

, Elon Musk, Podcast (February 2019)

In 2019 and 2020, Tesla's order page for "Full Self-Driving Capability" stated:

Coming later this year:
  • Recognize and respond to traffic lights and stop signs
  • Automatic driving on city streets.

In January 2020, Musk claimed the FSD software would be "feature complete" by the end of 2020, adding that feature complete "doesn't mean that features are working well". In August 2020, Musk stated that 200 software engineers, 100 hardware engineers and 500 "labelers" were working on Autopilot and FSD. In early 2021, Musk stated that Tesla would provide SAE Level 5 autonomy by the end of 2021. In a March 2021 conference call between Tesla and the California Department of Motor Vehicles (DMV), Tesla's director of Autopilot software revealed that Musk's comments "did not reflect engineering reality." Details of the call were made public via a Freedom of Information Act request by PlainSite. Speaking via video call at a 2023 AI conference held in Shanghai, Musk admitted that his former predictions were overly optimistic, and predicted that Tesla would finally realize fully autonomous vehicles at some point "later this year".

During the Q1 2024 investors meeting in early 2024, Musk announced that he would reveal a new robotaxi product in August 2024, but Tesla only received a permit to operate autonomous vehicles in Texas in August 2025.

Full Self-Driving (beta)

In October 2020, Tesla first released a beta version of its FSD software to early access program testers, a small group of users in the United States. Musk stated that the testing of FSD beta "[w]ill be extremely slow [and] cautious" and "be limited to a small number of people who are expert [and] careful drivers". The release of the beta program renewed concern regarding whether the technology is ready for testing on public roads. In January 2021, the number of employees and customers testing the beta FSD software was "nearly 1,000" expanding in May 2021 to several thousand employees and customers.

In October 2021, Tesla began the wide release of the FSD Beta to approximately 1,000 more drivers in the US, and the beta became accessible to Tesla drivers who achieved a 100 / 100 on a proprietary safety scoring system. By November 2021 there were about 11,700 FSD beta testers and about 150,000 vehicles using Tesla's safety score system, which then grew to 60,000 users participating in FSD beta by January 2022, and 100,000 users by April 2022. In November 2022, the FSD beta was opened to all North American owners who had purchased the option, regardless of safety score. As of February 2023, Tesla has about 360,000 participants in FSD Beta.

In February 2023, 362,758 vehicles equipped with the FSD Beta were recalled by the U.S. National Highway Traffic Safety Administration (NHTSA), and addition of new participants was halted by the company. In March 2023, FSD Beta v11.3.1, which also merged Autopilot code with FSD, was released as a fix for the issues. In July 2023, NHTSA asked Tesla to clarify which changes had been made, and when they were implemented. The NHTSA later reported 60 crashes and one fatality involving the use of FSD beta during the period August 2022 to August 2023.

In August 2023, Musk livestreamed a 45-minute demo of the upcoming version 12 of FSD, which he claimed used machine learning and not any human-written code. There was one intervention: the vehicle misinterpreted a green left-turn arrow as allowing forward traffic and nearly ran the red light before Musk intervened. Release notes for version 12.1 (an internal test version) and subsequent releases tout the removal of over 300,000 lines of explicit C++ code.

Full Self Driving (Supervised)

In April 2024, FSD version 12.3.3 replaced the word "beta" with "supervised" in its naming, and Tesla announced that users had driven over one billion miles (1.6 billion km) on FSD Beta. Version 12.3.3 introduced vision-based Autopark for vehicles with no ultrasonic sensors.

In March 2024, FSD version 12.3.6 started rolling out to an initial set of US customers, receiving positive feedback. Subsequently, Tesla announced a free one-month trial of FSD and Musk mandated demonstrating FSD to all prospective buyers in the US.

In May 2024, analysts of data released by YipitData found that, of the nearly 3,500 Tesla owners who trialed FSD in April 2024, only 2% kept their subscriptions.

The wide release of version 12.4.3 introduced the vision-based monitoring system for cars that have interior cameras, removing the need for torque-based attention monitoring.

In early September 2024, FSD version 12.5.3 introduced Actual Smart Summon and sunglasses support for the vision-based monitoring system. Shortly after, Tesla made some changes to its FSD package, changing the name from "Full Self-Driving Capability" to "Full Self-Driving (Supervised)" along with the description. At the end of September, Tesla released FSD version 12.5.5 for the Cybertruck, the defining feature of the release being the merging of the city and highway stacks.

The release of version 12.5.3 deviated from previous software releases. Previously, updates would roll out to HW3 vehicles before HW4 vehicles. Post-12.5.3, HW4 vehicles received updates at the same time as HW3 vehicles.

In late October 2024, version 12.5.6.1 was rolled out to HW4 vehicles, with general improvements such as the implementation of an end-to-end highway network, earlier and more natural lane change decisions, and new speed profiles.

In late November 2024, Tesla started to release different versions for HW3 versus HW4 vehicles; HW3 vehicles received version 12.6, and HW4 vehicles received FSD version 13.2. Version 12.6 features include speed profiles on higher-speed roads, end-to-end highway driving, and an improved controller, a feature from version 13. Version 13.2 featured major improvements to its end-to-end neural network. Highlights included reduced photon-to-control latency, integrated unpark and reverse capabilities, dynamic routing around road closures, and the ability to start FSD (Supervised) from Park. The update also introduced speed profile enhancements for city streets and highways, a redesigned controller for smoother tracking, and improved predictive modeling for collision avoidance. Tesla also adopted HW4-native inputs and announced plans for further scaling of model size, context length, and navigation features.

In January 2025, Tesla said its customers had driven three billion miles (4.8 billion km) on FSD (Supervised), and that it had increased artificial intelligence training compute capability by 400% in 2024.

In October 2025, Tesla released to the public FSD version 14.1.3 for HW4. New features include adjusted speed profiles, the removal of max speed set, and new arrival options which allow users to pick whether FSD should park curbside, in a parking lot, or in a driveway. A new profile was added called "Mad Max", which provides higher speeds and more aggressive lane changes compared to the existing "Hurry" mode.

In April 2026, Tesla announced plans to upgrade HW3 vehicles to version 14 "lite" beginning in late June 2026, and on June 29, Tesla started to push that version to some HW3 vehicles. These vehicles had been on FSD version 12.6.4 since early 2025.

In May 2026, Tesla said that vehicles had driven 10 billion miles (16 billion km) with FSD (Supervised), of which 3.7 billion miles (6.0 billion km) were on city streets.

On June 29, 2026, Tesla released v14 Lite to early access testers in the United States, to initial positive reviews. Days later, v14 Lite was given to early access testers in South Korea, making the country the first to receive FSD on HW3 vehicles outside of North America. A wide release began a few weeks later. In mid-August, v14.1 Lite was rolled out. The release of v14 Lite introduced a distilled v14 model designed for HW3, including features such as the "Start Self Driving" button, reversing, self-parking, and reinforcement learning.

Full Self Driving (Robotaxi)

On June 22, 2025, Tesla launched their commercial taxi service Robotaxi to a small group of invited users in Austin, Texas. Tesla said the vehicles were unmodified cars from their factory, with "Robotaxi" written on the front doors. Rides were priced at a flat rate of $4.20 within a geofenced area. While no one was in the driver's seat, a Tesla employee was still present in the front passenger seat for safety reasons. The service area in Austin has expanded four times since the initial launch and currently covers 245 square miles (630 km2).

On August 1, 2025, Tesla launched Robotaxi in San Francisco, although an employee is present in the driver seat due to legal requirements. The service area covers the entire Bay Area. As of March 2026, Tesla only has a permit in California for cars that have a Tesla-employed driver.

In September 2025, Tesla received regulatory approval to begin testing Robotaxi in Nevada and Arizona. In November 2025, Tesla received permits to begin operating Robotaxi in Arizona.

In late January 2026, Tesla launched Robotaxi services within Austin without a Tesla employee in the car. As of May 2026, Tesla is operating 22 fully driverless cars in Austin, six in Houston, and two in Dallas, during daylight and evening hours.

As of August 2026, Tesla Robotaxi vehicles are using FSD v15, which is not yet available for consumer cars. Musk described V15 as "a complete overhaul of the software architecture", with ten times the parameters of its predecessor, and including seven "core technologies" with 40% of them already running in the robotaxi fleet in Austin.

In September 2026, Tesla started offering paid Tesla Cybercab rides in Austin through the Robotaxi service. Users reported that the fee to use the Cybercab was noticeably less than for using the Model Y for the same route.

Autopilot version 9 enabled autonomous lane changes to pass vehicles moving below the set cruising speed; the most aggressive mode was named "Mad Max" after the media franchise.

05Regional availability

Outside of North America, autopilot capabilities differ. While Enhanced Autopilot and Full Self-Driving are offered to customers, their feature sets can be more limited depending on local regulations. Most regions offer Summon, Smart Summon, and Autopark with EAP and FSD. Following a roadmap released by the Tesla AI team in late 2024, FSD (Supervised) began rolling out to major international markets throughout 2025 and 2026.

Australia and New Zealand

In Australia and New Zealand, Autopilot, EAP, and FSD are available. In September 2025, Tesla launched FSD v13 in both countries, marking the first time the package was enabled in a right-hand drive market.

As of June 2026, Tesla expanded the regional rollout with FSD v14.3.3 exclusively for Hardware 4-equipped vehicles, bringing parity with the North American release stack. This version introduced upgraded neural networks, 20% faster reaction times, and a new "Sloth" speed profile. Autosteer on City Streets remains listed as upcoming for HW3-equipped cars. In April 2026, the FSD package also transitioned to a subscription-only model in the region.

Asia

China

In China, Autopilot, EAP, and FSD are available. As of 2025, FSD (Supervised) is available for HW4-equipped vehicles. For map data, Baidu Maps is utilized and data collected within China is currently required to remain in country.

In 2024, Tesla began testing FSD in China following preliminary approval. FSD was released to the public the next year. The Chinese version of FSD is unique as it utilizes a separate data set, specific for China.

South Korea

On November 26, 2025, Tesla enabled FSD v14.1.4 in South Korea for early access and influencers, making it the seventh country where the software was available. Currently, only owners of Model S and X equipped with Hardware 4 can use the feature.

In July 2026, Tesla announced and released FSD v14 Lite in South Korea for early access and influencers, making it the first non-North American country to have FSD enabled on HW3 vehicles. However, this release is currently restricted to US-built Model 3 and Y.

Europe

Autopilot functions have historically been only partially available in Europe due to strict UN ECE regulations, with features like auto lane change requiring driver confirmation.

In April 2026, the Dutch vehicle authority (RDW) granted type approval for FSD (Supervised) under an Article 39 exemption, allowing Tesla to release the software in the Netherlands. Through EU mutual recognition, Lithuania, Estonia, Denmark, and Belgium also approved and began rolling out FSD Supervised between May and June 2026. Larger markets such as Germany, France, and Italy are awaiting a coordinated EU-wide decision before permitting the software.

Since 2022, FSD has been in internal testing in Europe. In April 2024, a Swedish Transportation Administration official received a demonstration of FSD in Germany.

In September 2024, the UK’s Department for Transport raised concerns, stating “While [a driver assistance system] may help reduce collisions, it may also introduce new safety risks.”.

In November 2025, Tesla announced it was working with the Netherland's Dienst Wegverkeer (RDW) to gain approval for FSD's rollout in the country. Tesla is seeking an exemption for FSD to be approved as a new ⁠technology that existing rules do not properly cover, possible under Article 39 of Europe's motor vehicle approval law. Following the Netherlands' approval, other EU members are free to adopt the Dutch framework as their own. On April 10, 2026, RDW approved FSD (Supervised) for general traffic operation, making the Netherlands the first European country to do so. This approval was followed by Tesla announcing the end of the one-time purchase of FSD in Europe starting in May 2026.

On May 5, 2026 The Netherlands' RDW presented an update on their Article 39 FSD approval process to the EU's Technical Committee on Motor Vehicles (TCMV) and proposed the technology for broader European use with a provisional vote set for October 2026.

On May 18, 2026, the Lithuanian Transport Safety Administration approved FSD (Supervised) in Lithuania by recognizing the provisional type approval issued by the Dutch authorities. On 29 May 2026, the Estonian Transport Administration followed. On 9 June 2026, Denmark joined the list of European countries recognizing the RDW's provisional approval, followed by Belgium a day later.

On May 29, 2026, the European Transport Safety Council raised "substantive safety concerns" about Tesla’s FSD system due to risks of driver over-reliance, limited regulatory transparency, and a Reuters investigation alleging that Tesla’s published US safety statistics rely on flawed methodology that may overstate the system’s safety. It urged EU member states to "take a precautionary approach" in adopting rapid national authorisations.

06Tesla Dojo

Tesla Dojo is a supercomputer designed from the ground up by Tesla for computer vision video processing and recognition. It was planned to be used to train Tesla's machine learning models to improve FSD. In August 2025, Bloomberg News reported that Tesla shut down the Dojo project, although it was restarted in January 2026.

Dojo was first mentioned by Musk in April 2019 and August 2020. It was officially announced by Musk at Tesla's AI Day on August 19, 2021. In September 2021, a Tesla Dojo whitepaper was released. In August 2023, Tesla said that it started production use of Dojo, configured with 10,000 Nvidia chips.

Dojo consists of multiple cabinets. Each cabinet holds multiple, vertically arranged training tiles. Each tile holds multiple Tesla-designed D1 processing chips with associated memory. According to Tesla's senior director of Autopilot hardware, Ganesh Venkataramanan, "Tesla places 25 of these chips onto a single 'training tile', and 120 of these tiles come together... amounting to over an exaflop [a million teraflops] of power". (As of August 2021, Nvidia stated that the pre-Dojo Tesla AI-training center used 720 nodes of eight Nvidia A100 Tensor Core Graphics Processing Units (GPUs), 5,760 GPUs in total, for up to 1.8 exaflops of performance.) In April 2024, Musk said Tesla was using 35,000 Nvidia H100 chips, and was on track to have invested $10 billion cumulatively by the end of the year to train the neural network model for FSD.

07Driving features

Tesla's Autopilot is classified as Level 2 under the SAE six levels (0 to 5) of vehicle automation. At this level, the car can act autonomously, but requires the driver to monitor the driving at all times and be prepared to take control at a moment's notice. Tesla's owner's manual states that Autopilot should not be used on city streets or on roads where traffic conditions are constantly changing; however, some FSD capabilities "Traffic and Stop Sign Control (beta" such as "Autosteer on City Streets" are advertised for urban driving.

08Comparisons and evaluations

  • In 2018, Consumer Reports rated Tesla Autopilot as second best out of four (GM, Tesla, Nissan, Volvo) "partially automated driving systems". Autopilot scored highly for its capabilities and ease of use, but was worse at keeping the driver engaged than the other manufacturers' systems. Consumer Reports also found multiple problems with Autopilot's automatic lane change function, such as cutting too closely in front of other cars and passing on the right.
  • In 2018, the Insurance Institute for Highway Safety (IIHS) compared Tesla, BMW, Mercedes and Volvo "advanced driver assistance systems" and stated that the Tesla Model 3 experienced the fewest incidents of crossing over a lane line, touching a lane line, or disengaging.
  • In February 2020, Car and Driver compared GM's Super Cruise, comma.ai and Autopilot. They called Autopilot "one of the best", highlighting its user interface and versatility, but criticizing it for swerving abruptly.
  • In June 2020, Digital Trends compared GM's Super Cruise self-driving and Tesla Autopilot. The conclusion: "Super Cruise is more advanced, while Autopilot is more comprehensive."
  • In October 2020, the European New Car Assessment Program gave the Tesla Model 3 Autopilot a score of "moderate".
  • Also in October 2020, Consumer Reports evaluated 17 driver assistance systems, and concluded that Tesla Autopilot was "a distant second" behind GM's Super Cruise, although Autopilot was ranked first in the "Capabilities and Performance" and "Ease of Use" categories.
  • In February 2021, a MotorTrend review compared GM's Super Cruise and Autopilot and said Super Cruise was better, primarily due to safety.
  • In May 2021, consulting firm Guidehouse Insights ranked Tesla Full Self-Driving last in strategy and execution among 15 companies.
  • In January 2023, Consumer Reports rated "active driving assistance systems" and ranked Tesla Autopilot as 7th out of 12. The Full Self-Driving package was not tested.
  • In October 2023, Consumer Reports rated "active driving assistance systems" and ranked Tesla Autopilot as 8th out of 17. The Full Self-Driving package was not tested.
  • In December 2023, TechCrunch ranked Full Self-Driving version 11 last out of five systems evaluated, saying "it's pretty easy to choose a loser. Three years after its initial beta release, Tesla's supposed Full Self-Driving still doesn't live up to its name", adding "the FSD beta software [was] frequently confused on urban and rural streets" and "Tesla's driver monitoring was by far the most lax of those tested".
  • In March 2024, IIHS reported its first "partial automation safeguard ratings", ranking Tesla Autopilot and Full Self-Driving version 11 as "poor", along with 9 of 12 other systems.
  • In January 2026, MotorTrend evaluated Ford BlueCruise, GM Super Cruise, Hyundai Drive Assist, and BMW Highway Assistant, and said that Tesla Full Self-Driving was the best driver assistance system on the market, "and it isn't very close ... v14 ... is vastly improved over ... v12 ... No other ADAS on the market today can ... drive on most roads".
  • In May 2026, the NHTSA said that Tesla Model Ys built on or after November 12, 2025 were the first vehicles to pass the agency’s new model year (MY) 2027 benchmark for advanced driver assistance systems. The benchmarks include: automatic emergency braking, pedestrian automatic emergency braking (day and night), lane keeping assist, blind spot warning, and blind spot intervention.

09Criticism

Tesla's self-driving strategy has been criticized as dangerous and obsolete, and was abandoned by other companies years ago. Most experts believe that Tesla's approach of trying to achieve autonomous vehicles by eschewing high-definition maps and lidar is not feasible. Auto analyst Brad Templeton has criticized Tesla's approach by arguing, "The no-map approach involves forgetting what was learned before and doing it all again." In a May 2021 study by Guidehouse Insights, Tesla was ranked last for both strategy and execution in the autonomous driving sector. Some news reports in 2019 state "practically everyone views [lidar] as an essential ingredient for self-driving cars" and "experts and proponents say it adds depth and vision where camera and radar alone fall short." Similarly, in 2026, Waymo founder John Krafcik stated Tesla's camera-only approach, along with their limited resolution and wide field of view, gave the system myopia and made it worse than a human driver.

An August 2021 study conducted by Missy Cummings et al. found three Tesla Model 3 cars exhibited "significant between and within vehicle variation on a number of metrics related to driver monitoring, alerting, and safe operation of the underlying autonomy... suggest[ing] that the performance of the underlying artificial intelligence and computer vision systems was extremely variable."

In September 2021, legal scholars William Widen and Philip Koopman argued that Tesla's advertising of FSD as an SAE Level 2 system was misleading to "avoid regulatory oversight and permitting processes required of more highly automated vehicles". Instead, they argued FSD should be considered a SAE Level 4 technology and urged state departments of transportation in the U.S. to classify it as such, since publicly available videos show that "beta test drivers operate their vehicles as if to validate SAE Level 4 (high driving automation) features, often revealing dramatically risky situations created by use of the vehicles in this manner."

In March 2025, YouTuber Mark Rober conducted a test to see if a Tesla would avoid hitting a child mannequin in conditions such as fog and heavy rain. Another test involved placing the mannequin behind a wall covered with an image of the road. The Tesla, unlike the comparison vehicle equipped with LiDAR technology, failed these tests. Some have criticized these tests, noting issues such as the vehicle's older hardware and the fact that the video's title was misleading. The title implied the testing of the vehicle's "Full Self Driving" features, but was instead utilizing Autopilot (Tesla's branding of cruise control) and its older code.

Protestors against Tesla's deployment of its trial robotaxi service in Austin, Texas, attended a June 2025 demonstration of the limitations of FSD (Supervised) hosted by Tesla Takedown and The Dawn Project.

As of June 2026, Tesla does not provide any insurance in case of an accident while using the self-driving features, whereas one of its competitors has started to do so.

10Safety statistics and concerns

Safety statistics

Tesla claims that its driver-assistance features improve safety and reduce accidents caused by driver fatigue or inattention. However, collisions and fatalities involving Autopilot have attracted scrutiny from media and regulators. Industry experts and safety advocates have raised concerns about the deployment of beta software to the general public, calling the practice risky and potentially irresponsible.

In April 2016, Elon Musk stated the probability of an accident was at least 50% lower when using Autopilot without citing any references. At the time, it was estimated that collectively, Teslas had been driven for 47 million miles (76 million km) in Autopilot mode. After the first widely publicized fatal Autopilot crash in May 2016 which occurred in Williston, Florida, Tesla acknowledged the death and published a blog in June, comparing the average fatality rate in the United States (at the time, one per 94 million miles (151 million km)) and worldwide (one per 60 million miles (97 million km)) with that of Tesla Autopilot (one per 130 million miles (210 million km)); Tesla stated in July that "customers using Autopilot are statistically safer than those not using it at all", "the [Autopilot] system provided a net safety benefit to society", and "the 'better-than-human' threshold had been crossed and robustly validated internally". Tesla's statistical approach was criticized as comparing two different datasets; while Autopilot is limited to highway driving, the overall death rate for the United States includes more varied driving conditions. In addition, Tesla's vehicles were larger and more expensive than most vehicles on the road, making them generally safer in a crash. Other factors that could have affected the data include weather conditions and Tesla owner demographics.

Fortune criticized the sale of US$2 billion in Tesla stock, noted the sale occurred less than two weeks after "immediately" reporting the fatal early May crash to the NHTSA, but before Tesla posted its public acknowledgement of the crash in late June; the article stated that "Tesla and Musk did not disclose the very material fact that a man had died while using an auto-pilot technology that Tesla had marketed vigorously as safe and important to its customers." Musk responded to the article with a statistical argument in an email to the reporter, saying "Indeed, if anyone bothered to do the math (obviously, you did not) they would realize that of the over 1M auto deaths per year worldwide, approximately half a million people would have been saved if the Tesla autopilot was universally available. Please, take 5 mins and do the bloody math before you write an article that misleads the public."

Following the Williston crash, NHTSA released a preliminary report in January 2017 stating "the Tesla vehicles' crash rate dropped by almost 40 percent after Autosteer installation." NHTSA did not release the data until November 2018. A private company, Quality Control Systems, released a report in February 2019 analyzing the same data, stating the NHTSA conclusion was "not well-founded". Part of the data verification included scrutiny of the 43,781 vehicles NHTSA claimed had Autosteer installed; of those, only 5,714 had an exact odometer reading at the time that Autosteer was installed and airbag deployment data; collectively, the data for those 5,714 vehicles showed 32 airbag deployments in the 42,001,217 mi (67,594,407 km) traveled before installation, and 64 airbag deployments in the 52,842,182 mi (85,041,249 km) after. That means the crash rate, as measured by the rate of airbag deployments per million miles of travel, actually increased from 0.76 to 1.21 after the installation of Autosteer, an increase of 59%.

Starting in 2018, Tesla began publishing safety statistics on a quarterly basis, using the values to demonstrate decreased accident rates while using Autopilot. The data have been difficult to interpret, as the actual crash counts, baseline mileage, and basic definition of a crash are not available. Because of this lack of accurate reporting, Green Car Reports noted that "While these updated numbers for Autopilot are encouraging, it's clear that Tesla's claims of its vastly superior safety, at least in terms of fatal accidents, are still vapor. It's way too soon to come to any firm conclusions about Autopilot safety."

In February 2020, Andrej Karpathy, Tesla's head of AI and computer vision, stated that Tesla cars have driven three billion miles (4.8 billion km) on Autopilot, of which one billion miles (1.6 billion km) have been driven using Navigate on Autopilot; Tesla cars have performed 200,000 automated lane changes; and 1.2 million Smart Summon sessions have been initiated with Tesla cars. He also stated that Tesla cars are avoiding pedestrian accidents at a rate of tens to hundreds per day. The company stopped publishing safety statistics in 2022, but resumed in January 2023. The first comparable safety statistics using Full Self-Driving were released in March 2023; Tesla stated that vehicles operating under FSD experienced a crash that deployed the airbag approximately every 3.2 million miles (5.1 million km), compared to all crashes with airbag deployment reported to the police, which occur approximately every 0.6 million miles (0.97 million km).

Additionally, a statistical analysis first published as a preprint in 2021 and in final form in 2023 criticized the self-reported Tesla crash rate data, as it failed to account for vehicle owner demographics as well as the types of roads on which Autopilot was being operated. While the government baseline crash rate used as a comparison drew from vehicles of all ages, operating on roads ranging from highways, rural roads, and city streets, Tesla vehicles are relatively newer and Autopilot is limited to operations on freeways and highways. When adjusted for driver age and road type, Autopilot crash rates were found to be nearly the same as using "active safety features" only.

An MIT study published in September 2021 found that Autopilot is not as safe as Tesla claims, and led to drivers becoming inattentive.

Fatal and nonfatal crashes

After Tesla software version 7.0 was released in October 2015 and Tesla claimed Autopilot would "[relieve] drivers of the most tedious and potentially dangerous aspects of road travel", the first fatal crashes involving Autopilot occurred less than a year later, in China (January 2016) and the United States (May 2016). Tesla stated it had immediately informed the NHTSA about the US crash in May, but the NHTSA did not announce it until June 30, 2016, when it was widely reported as the first Autopilot-related fatality; the death in China was not reported in the US until that September, and Tesla stated that damage prevented it from confirming if Autopilot was engaged.

The first Autopilot death in the US occurred after the Tesla collided with the side of a semi-trailer truck and underrode that vehicle's trailer, shearing off the greenhouse. After the fatality, Tesla stated that Autopilot failed to recognize the white trailer against a bright sky. Musk reported that improvements to Autopilot in September 2016 would "[make] much more effective use of radar" and "very likely" would have prevented the fatal accident. Despite these improvements, the shift to a different hardware platform, and additional updates to Autopilot, another fatal crash in May 2019 occurred when a Tesla again underrode the side of a trailer. Five years after the first fatalities, in 2021, Tesla began transitioning to "Tesla Vision" by removing the radar from new Model 3 and Y vehicles; in 2023, The Washington Post reported that Musk had pushed for a camera-only approach over the objections of Tesla engineers.

As of October 2024, there have been fifty-one reported fatalities involving Tesla's Autopilot function, forty-four verified by NHTSA or expert testimony, and two verified as involving FSD. Other deadly incidents involving suspected Autopilot use remain outstanding. Many of these incidents have received varying degrees of attention from news publications. Additionally, the NHTSA cited hundreds of nonfatal accidents in official documents. In addition to failing to recognize the side of a trailer, Autopilot crashes have been blamed on driver distraction, inability to detect stationary emergency vehicles, and misuse outside the stated operational design domain of "controlled-access highways [...] with a center divider, clear lane markings, and no cross traffic".

General concerns

The National Transportation Safety Board (NTSB) criticized Tesla's lack of system safeguards in a fatal 2018 Autopilot crash in California, and for failing to foresee and prevent "predictable abuse" of Autopilot. Following this collective criticism amid increased regulatory scrutiny of ADAS systems, especially Tesla Autopilot, in June 2021, the NHTSA announced an order requiring automakers to report crashes involving vehicles equipped with ADAS features in the United States. In April 2024, the NHTSA released the findings of a 3-year investigation of 956 vehicle collisions in which Tesla Autopilot was thought to have been in use that found that the system had contributed to at least 467 collisions including 13 that resulted in fatalities.

Driver monitoring

Musk stated in October 2015 that "we're advising drivers to keep their hands on the wheel [when Autopilot is engaged]". Despite this, multiple videos were posted to YouTube at the time showing drivers using Autopilot to drive hands-free, including Musk's ex-wife Talulah Riley. Other drivers have been found sleeping at the wheel, driving under the influence of alcohol, and performing other inappropriate tasks with Autopilot engaged. As initially released, the Autopilot system uses a torque sensor to detect if the driver's hands were on the steering wheel and gives audible and visual warnings for the driver to take the wheel when no torque is detected, but several owners confirmed they could drive for several minutes hands-free before receiving a warning. At least one device designed to defeat the torque sensor was ordered by NHTSA to discontinue sales in 2018. Initially, Tesla decided against adding more advanced driver monitoring options to ensure drivers remained engaged with the driving task.

In late May 2021, a new version of the software enabled driver-facing cameras inside new Model 3 and Model Y (i.e. the first cars as part of the switch to Tesla Vision) to monitor driver attentiveness while using Autopilot. Model S and Model X cars made before 2021 do not have an inside camera and therefore physically cannot offer such capabilities, although the refreshed versions are expected to have one. A review of the in-cabin camera-based monitoring system by Consumer Reports found that drivers could still use Autopilot even when looking away from the road or using their phones, and could also enable FSD beta software "with the camera covered."

In 2022, Musk agreed to a proposal on Twitter that "users with more than 10,000 miles on FSD Beta should be given the option to turn off the steering wheel nag", saying the system would be updated in January 2023. In April, Musk confirmed the nag was being reduced gradually. That June, a hacker discovered that FSD Beta had an undocumented mode which disables all driver monitoring. The NHTSA wrote a letter to Tesla under the authority of EA 22-002 on July 26, noting the new mode "could lead to greater driver inattention and failure of the driver to properly supervise Autopilot". The letter was attached a Special Order requesting when the software was updated with the hidden mode, detailed steps or conditions required to unlock that mode, and the reasons why Tesla issued the updates. Tesla responded by August 25; the response was considered confidential and no public version is available.

A "nag elimination" module sold as an aftermarket accessory automatically adjusts the volume from the steering wheel, which is registered as steering wheel input, allowing drivers to take their hands off the wheel. Anecdotal evidence has shown the module is effective only for Tesla vehicles sold in the United States and Canada, leading to speculation the driver monitoring software is different by region. Doll heads have been used to fool the monitoring camera into believing that the driver is paying attention, which is not possible with most other ADAS systems.

Detecting stationary vehicles at speed

Autopilot may not detect stationary vehicles; the manual states: "Traffic-Aware Cruise Control cannot detect all objects and may not brake/decelerate for stationary vehicles, especially in situations when you are driving over 50 mph (80 km/h) and a vehicle you are following moves out of your driving path and a stationary vehicle or object is in front of you instead." This has led to numerous crashes with stopped emergency vehicles.

Dangerous and unexpected behavior

In a 2019 Bloomberg survey, hundreds of Tesla owners reported dangerous behaviors with Autopilot, such as phantom braking, veering out of lane, or failing to stop for road hazards. Autopilot users have also reported the software crashing and turning off suddenly, collisions with off ramp barriers, radar failures, unexpected swerving, tailgating, and uneven speed changes.

Ars Technica notes that the brake system tends to initiate later than some drivers expect. One driver claimed that Tesla's Autopilot failed to brake, resulting in collisions, but Tesla pointed out that the driver deactivated the cruise control of the car prior to the crash. The automatic emergency braking (AEB) system also initiates sooner than some drivers expect due to a software error, which led to a recall in 2021 for false activation of the AEB system.

Ars Technica also noted that while lane changes may be semi-automatic (if Autopilot is on, and the vehicle detects slow moving cars or if it is required to stay on route, the car may automatically change lanes without any driver input), the driver must show the car that he or she is paying attention by touching the steering wheel before the car makes the change. In 2019, Consumer Reports noted that Tesla's automatic lane-change feature is "far less competent than a human driver".

Data collection and privacy

Most modern vehicles, including Teslas, are equipped with event data recorders which collect vehicle data to aid investigations and diagnostics. Data collected includes speed, acceleration, brake use, steering input, and driver assistance feature status. Tesla vehicles permanently record this data as "gateway log" files onto a microSD card in the Media Control Unit, at a rate of approximately 5 times per second (hertz or Hz). Gateway log files are uploaded to Tesla when the vehicle connects to a Wi-Fi network.

The Autopilot computer stores images (for all vehicles) and video (for model years 2016 and later) along with driving data similar to that captured in gateway log files at a higher temporal resolution (up to 50 Hz) and uploads these to Tesla periodically. These "snapshots" are deleted locally after being uploaded. Tesla has been silent about its data retention policies. Snapshot data are always captured when the vehicle crashes (defined as deploying the airbags) and are uploaded via a 4G cellular connection. Snapshots sometimes also are captured for other events defined by Tesla.

Even when Autopilot is not actively providing steering, throttle, and brake controls, 2016 and later model year Teslas operate Autopilot in "Shadow Mode". When the control inputs generated by the shadow mode Autopilot do not match those of the human driver, the vehicle may record a snapshot to assist in training the system, after which the data may be reviewed by the Autopilot team. As explained by Karpathy, Tesla can deploy additional software "detectors" triggered by specific situations identified by snapshot data, which then upload camera and other data to Tesla when similar situations are detected. These data are used to revise the existing detectors.

For vehicles built after mid-2017, the Autopilot computer also records "trail" data, including the car's route as determined by GPS "breadcrumbs" for the entire trip. A trip starts when the vehicle shifts from Park to Drive, and ends when shifted back to Park. Trail data also includes vehicle speed, road type used, and Autopilot status. Like the snapshots, these trail data are deleted locally after being uploaded to Tesla. The trail data are meant to be anonymized by stripping the vehicle identification number (VIN) and assigning a temporary identifier, but the same temporary identifier can be assigned to a single vehicle for several weeks.

Under Tesla's privacy policies, the company does not sell customer and vehicle data, but may share the data with government entities. The Mozilla Foundation ranked Tesla as the worst of 25 car brands, receiving sub-standard scores on all of the foundation's privacy and security criteria.

Tesla Vision relies on the "Autopilot labeling team", who view short video clips recorded by vehicle cameras and label visible signs and objects, training the machine vision interpreter.

Data labeling was first handled by a non-profit outsourcing company named Samasource, which initially provided 20 workers in Nairobi, Kenya. The Nairobi team grew to 400 workers by 2016, but Karpathy later stated the "quality [of their work] was not amazing" and Tesla began hiring employees for data labeling in San Mateo, California instead.

In April 2023, it was revealed that San Mateo labeling employees had shared clips internally among themselves, including recordings of privately owned areas such as garages, as well as crashes, road-rage incidents, and meme videos annotated with "amusing captions or commentary". Former Tesla employees described the San Mateo office atmosphere as "free-wheeling" and noted "people who got promoted to lead positions shared a lot of these funny [clips] and gained notoriety for being funny." In one case, the submersible Lotus Esprit prop featured in the James Bond film The Spy Who Loved Me, which had been purchased by Elon Musk in 2013 and stored in his garage, was recorded and shared by labeling team members. Because sharing these clips was apparently for entertainment and not related to Autopilot training, Carlo Plitz, a data privacy lawyer, noted "it would be difficult to find a legal justification" for doing so. After the San Mateo office was closed in June 2022, the labeling team moved to Buffalo, New York, where Tesla has a total of 675 employees, hundreds of whom are labelers.
