- The US government released long-awaited data on car crashes involving driver-assistance systems.
- Teslas on Autopilot accounted for 273 of the 392 crashes reported since last July.
- The report omits key information, making it difficult to draw a comparison between technologies.
Vehicles using Tesla’s Autopilot software were involved in 273 crashes over roughly the last year, according to a report released Wednesday by the US road-safety regulator.
The report from the National Highway Traffic Safety Administration offers the clearest picture yet of how bleeding-edge advanced driver-assistance systems (ADAS) from Tesla and others perform on US roads. ADAS features can automate vehicle functions like steering, braking, and acceleration but stop short of making a car fully autonomous.
The data comes from an order NHTSA gave to automakers last June instructing them to report any incidents involving their driver-assistance technologies, known as Level 2 systems. Regulators also told autonomous-vehicle companies like Waymo to share information about crashes as they occur.
Automakers reported 392 crashes involving their ADAS systems in total, with Tesla logging by far the most. Honda was next with 90 crashes. Subaru had 10, Ford had five, and Toyota had four. Seven other carmakers reported three or fewer incidents.

The research is part of a broader effort by the US government to understand the risks and safety benefits of ADAS features, which are becoming increasingly common and which encourage drivers to yield an increasing array of driving tasks to their vehicles, from parking to changing lanes.
Without crucial information about how many ADAS-equipped vehicles each manufacturer has on the road and the number of miles they travel, it’s impossible to say whether one system crashes more frequently than another.
Every vehicle Tesla sells comes with Autopilot, which enables a car to automatically follow lane lines and maintain a set distance to the car ahead. Other manufacturers typically offer their comparable features as options, which may skew the data in their favor.
NHTSA also warned that some manufacturers can access crash data more readily, which may impact the data.
Self-driving vehicles were involved in 130 incidents, NHTSA said in a separate report. Waymo, the Google-owned startup that is experimenting with driverless taxis, reported the most: 62 incidents.
A Waymo spokesperson said: “We see value in having nationally standardized and uniform crash reporting during this early stage of the development and deployment of autonomous driving technology, and there’s public benefit in NHTSA sharing its findings. We also believe any reporting requirements should be harmonized across all U.S. jurisdictions to limit confusion and potentially enable more meaningful comparisons, and NHTSA’s effort is a step toward achieving that goal.”
