According to the latest data available for Tesla’s autopilot feature, the company has registered one accident for every 4.53 million miles driven in autopilot mode in the United States. For those driving a Tesla without Autopilot and without the active safety features, the company registered one accident for every 1.56 million miles driven. By comparison, NHTSA’s most recent data shows that in the United States there is one automobile crash every 479,000 miles.
Tesla engineers their vehicles to be the safest cars in the world. The company’s use of passive safety, active safety, and automated driver assistance is crucial for keeping not just Tesla drivers and passengers safe, but all drivers on the road safe.
Tesla’s Model S, Model X and Model 3 have achieved the lowest overall probability of injury of any vehicle ever tested by the U.S. government’s New Car Assessment Program. Much of this has to do with the rigid, fortified structure of the battery pack that is mounted to a car’s floor, which provides a vehicle with exceptional strength, large crumple zones, and a uniquely low center of gravity. Because of their strength, Tesla’s battery packs rarely incur serious damage in accidents. And, in the unlikely event that a fire occurs, the state-of-the-art design of our battery packs ensures that its safety system works as intended and isolates a fire to select areas within the battery while simultaneously venting heat away from the passenger cabin and the vehicle.
Active safety features come standard on all Tesla vehicles made after September 2014 for an added layer of safety beyond the physical structure of each car. Because every Tesla is connected, the company can use the billions of miles of real-world data from their global fleet – of which over 1 billion have been driven with Autopilot engaged – to understand the unique ways accidents happen. Through this data, the company then develops features that can help Tesla drivers mitigate or avoid accidents. Through over-the-air software updates, Tesla can introduce safety features and enhancements long after a car has been delivered, and release updated versions of existing safety features that take into account the most up-to-date real-world data collected by all the Teslas on the road.
In October 2018, Tesla began voluntarily releasing quarterly safety data to provide critical safety information about our vehicles to the public, and in July 2019 they began voluntarily releasing annually updated data about vehicle fires. Accident rates among all vehicles on the road can vary from quarter to quarter and can be affected by seasonality, like reduced daylight and inclement weather conditions.
