‘A very big deal’: Federal safety regulator takes aim at Tesla Autopilot

FILE - In this March 23, 2018, file photo provided by KTVU, emergency personnel work a the scene where a Tesla electric SUV crashed into a barrier on U.S. Highway 101 in Mountain View, Calif. The Apple engineer who died when his Tesla Model X crashed into the concrete barrier complained before his death that the SUV's Autopilot system would malfunction in the area where the crash happened. The driver of another Tesla involved in a fatal crash that California highway authorities said may have been on operating on Autopilot posted social media videos of himself riding in the vehicle without his hands on the wheel or foot on the pedal. The May 5, 2021, crash in Fontana, a city 50 miles (80 kilometers) east of Los Angeles, is also under investigation by the National Highway Traffic Safety Administration. The probe is the 29th case involving a Tesla that the federal agency has probed. (KTVU-TV via AP, File)
