DENVER (AP) — The widow of a man who died after his Tesla veered off the road and crashed into a tree while he was using its partially automated driving system is suing the carmaker, claiming its marketing of the technology is dangerously misleading.

The Autopilot system prevented Hans Von Ohain from being able to keep his Model 3 Tesla on a Colorado road in 2022, according to the lawsuit filed by Nora Bass in state court on May 3. Von Ohain died after the car hit a tree and burst into flames, but a passenger was able to escape, the suit says.

Von Ohain was intoxicated at the time of the crash, according to a Colorado State Patrol report.

The Associated Press sent an email to Tesla’s communications department seeking comment Friday.

Tesla offers two partially automated systems, Autopilot and a more sophisticated “Full Self Driving,” but the company says neither can drive itself, despite their names.
