Tesla autopilot stirs U.S. alarm as 'disaster waiting to happen'

Derrick Monet and his wife, Jenna, were driving on an Indiana interstate in 2019 when their Tesla Model 3 sedan operating on Autopilot crashed into a parked fire truck. Derrick, then 25, sustained spine, neck, shoulder, rib and leg fractures. Jenna, 23, died at the hospital. The incident was one of a dozen in the last four years in which Teslas using this driver-assistance system collided with first-responder vehicles, raising questions about the safety of technology the world's most valuable car company considers one of its crown jewels. Now, U.S. regulators are applying greater scrutiny to Autopilot than ever before.
