The probe was begun for the first time in August 2021. Since then, the NHTSA has requested information from Tesla and 12 other manufacturers on their Level 2 driver assist systems, which allow the car to regulate steering, braking, and accelerating on particular road types at the same time.
The agency is looking for information on kilometers driven as well as crash reports. Separately, the NHTSA is gathering crash data from a larger group of firms that make driver assist systems and fully autonomous vehicles.
