The U.S. government’s highway safety agency wants detailed information on how Tesla’s Autopilot system detects and responds to emergency vehicles parked on highways.
The National Highway Traffic Safety Administration made the request in an 11-page letter dated Aug. 31 that was sent to the electric carmaker .
The letter is part of an investigation into how the company’s partially automated driving system behaves when first responder vehicles are parked while crews deal with crashes or other hazards.
