A Tesla was operating on an automated driving system when it crashed into a firetruck in California last month, killing the driver and critically injuring a passenger. The National Highway Traffic Safety Administration said Wednesday it has dispatched a special crash investigation team to look into the Feb. 18 crash in Northern California where emergency responders had to cut open the Tesla to remove the passenger. Four Contra Costa County firefighters had minor injuries. The probe is part of a larger investigation by the agency into multiple instances of Teslas on Autopilot crashing into parked emergency vehicles that are tending to other crashes.
