A Tesla Model S travelling at 65 mph crashed into the back of a stationary fire engine on a California highway. 

No injuries were recorded, and the driver subsequently claimed his car was on Autopilot at the time of the accident. 

Bloomberg reported that the federal government is “gathering information” on the accident, but had yet to decide to formally open an investigation.

The incident raised questions about the safety of Tesla's Autopilot system and the adequacy of its communication about its limitations to customers.
