Tesla FSD — Level 2 Under the Name "Full Self-Driving"

Tesla FSD (Full Self-Driving) is driver-assistance software that Tesla sells as an option. Despite the name, Tesla's own recall filing with NHTSA describes it as an SAE Level 2 driver support feature: the driver must supervise it at all times and take over when needed. "FSD Beta", which steers the car on city streets and through intersections, first reached a small group of owners on the night of 20 October 2020, North American time. At the end of March 2024 it was renamed "FSD (Supervised)", and in 2026 European approvals began. As of spring 2026 it was still not available in Japan, where Tesla's Japanese arm said it aimed to introduce it during 2026.

Where Level 2 driver assistance itself began is covered on the Autopilot page, rolled out in 2015. This page covers the feature built on top of it under the name "FSD", and the regulatory fight over it.

2016: "full self-driving hardware" and a pre-sold option

In a blog post on 19 October 2016, Tesla announced that from that day every car it produced, Model 3 included, would carry the hardware needed for full self-driving capability at a safety level substantially greater than a human driver. The suite consisted of eight cameras giving 360-degree visibility at up to 250 metres, twelve ultrasonic sensors, a forward radar, and an onboard computer with more than 40 times the power of the previous generation, running a Tesla-developed neural network for vision, sonar and radar. The post also said Tesla would first calibrate the system on millions of miles of real-world driving before switching on the features the new hardware enabled.

According to Electrek, from 2016, when this second-generation hardware went into its cars, Tesla pre-sold a "Full Self-Driving Capability" package promising eventual full autonomy. As of 2018 it cost $3,000 at the time of order, on top of the $5,000 Enhanced Autopilot package. Paying for a feature that did nothing yet at the time of purchase became the starting point of the later dispute.

October 2020: the FSD Beta release

According to a Drive Tesla article dated 21 October 2020, Tesla had released "FSD Beta" the previous night to members of its Early Access Program. The software version was 2020.40.8.10, and the release notes urged owners to pay attention at all times, be ready to take over and not become complacent. Early Access members usually sign non-disclosure agreements, but this time some owners were allowed to post about it on social media.

The rollout then unfolded as follows.

Japan was not in the first wave, and as of reporting in April 2026 the feature was still not available to the general public there.

The 2023 recall: "Level 2" in Tesla's own words

On 15 February 2023 Tesla filed recall 23V-085 with NHTSA, covering 362,758 vehicles, including 2016–2023 Model S, that had installed or were due to install FSD Beta. The report opens by stating that FSD Beta is an SAE Level 2 driver support feature, and that while it is engaged the driver is responsible for operating the vehicle and must constantly supervise it and intervene as needed.

The defect described four situations in which the feature could infringe local traffic laws or customs: travelling through certain intersections on a stale yellow light, the length of a stop at stop signs, adjusting speed through variable speed zones, and changing lanes out of certain turn-only lanes to continue straight. The remedy was an over-the-air software update.

NHTSA's scrutiny continued. On 17 October 2024 it opened a preliminary evaluation covering about 2.41 million vehicles into crashes in reduced roadway visibility caused by sun glare, fog or airborne dust. It was prompted by four crashes; in one of them a pedestrian was killed. On 7 October 2025 it opened another, covering about 2.88 million vehicles, into FSD running red lights and steering into opposing lanes. That document notes that Tesla itself characterises FSD as a Level 2 partial automation system requiring a fully attentive driver.

The fight over the name

The name stayed in dispute with regulators. On 16 December 2025 the California DMV ruled that marketing using the terms "Full Self-Driving Capability" and "autopilot" was misleading and violated state law. According to the DMV, Tesla had meanwhile dropped "Full Self-Driving Capability" and switched to "Full Self-Driving (Supervised)" to signal that driver supervision is required. How the Autopilot name was handled is on the Autopilot page.

Europe replayed the argument. According to electrive, the Dutch RDW approved FSD (Supervised) in April 2026, and Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia and Slovakia recognised that approval. Outside Europe it is approved in North America as well as Australia, New Zealand and South Korea. But the Dutch decision is a provisional EU type approval, and the EU-wide vote has been postponed repeatedly, most recently to December. Germany's transport minister called the name FSD misleading, and Tesla renamed the system "Tesla Assisted Driving" in Europe. The ministry said it is not a system that takes over the full driving task and that the driver must remain attentive at all times.

In China, Tesla began rolling out features similar to US FSD on 25 February 2025, but CnEVPost reported little progress since. In January 2026 CEO Elon Musk said he expected approval in February; the state-run China Daily denied this, citing a government source. In its April 2026 results Tesla said only that it was working to launch FSD in China as soon as possible.

In Japan, according to Car Watch, Tesla's Japanese arm began test drives in a Model 3 on 20 August 2025 and said the release date depends on development and regulatory approval. ITmedia reported in April 2026, citing the Nikkei, that the company's president, Hashimoto, said it aimed to introduce the feature during 2026.

Social impact: who is doing the testing?

The way FSD is sold changed how car safety gets established. A fully driverless service such as Waymo tests with the operator's own cars and staff, and carries the public only after regulators grant permits. FSD is used on public roads by ordinary owners who have paid for it and who carry the driver's responsibility. Tesla presents this as a data advantage: according to CnEVPost, it says FSD has driven more than 9.38 billion cumulative miles, a company figure. According to Car Watch, Tesla says that with v13 it abandoned its earlier rule-based algorithms and trains on more than a billion miles of driving data collected from more than six million cars.

Other drivers and pedestrians, however, never agreed to take part in a test. NHTSA's investigations are about exactly those people around FSD-equipped cars. Buyers face a question too: whether the promised feature will ever arrive. According to CarNewsChina, the FSD package is sold in China as a one-time purchase for 64,000 yuan, while Drive Tesla Canada reports that Chinese owners still lack the v14 experience available in North America. In the US, as Musk had announced, outright purchase ended after 14 February 2026, leaving only a $99-a-month subscription. According to TFLcar, Tesla's CFO said paying FSD customers made up about 12% of the company's fleet. Tesla's second-quarter 2026 update put active FSD subscriptions, counting both upfront purchases and monthly plans, at 1.48 million, and said over 55% of new deliveries in North America included FSD subscriptions.

In April 2026 Musk said unsupervised FSD would begin a phased rollout to customer cars in the fourth quarter of 2026 (CnEVPost). How often such deadlines have slipped is summarised on the Tesla robotaxi page. A decade after 2016, the gap between what the name promises and what regulators recognise has not closed.

The wider story is in the autonomous driving timeline, and the definitions of automation levels are on the SAE levels of driving automation page. See also Elon Musk.
