Tesla's Autopilot faces US investigation after crashes with emergency vehicles

The US government has opened a formal investigation into Tesla's Autopilot partially automated driving system after a series of collisions with parked emergency vehicles. The investigation covers 765,000 vehicles, almost everything that Tesla has sold in the US since the start of the 2014 model year. Of the crashes identified by the National Highway Traffic Safety Administration (NHTSA) as part of the investigation, 17 people were injured and one was killed. NHTSA says it has identified 11 crashes since 2018 in which Teslas on Autopilot or Traffic Aware Cruise Control have hit vehicles at scenes where first responders used flashing lights, flares, an illuminated arrow board or cones warning of hazards. The agency announced the action on Monday in a posting on its website.
