Experts say both cases raise pressure on the National Highway Traffic Safety Administration to take action on Tesla's partially automated driving system called Autopilot, which has been involved in multiple crashes that have resulted in at least three U.S. deaths. The probe of the May 5 crash in Fontana, California, east of Los Angeles, is the 29th case involving a Tesla that the agency has responded to.
