Washington DC - Tesla has been removed from the investigation into a fatal crash involving one of its autopiloted cars.
The company was barred from the investigation on Thursday after it released information before it had been checked by the National Transportation Safety Board.
Board chairman Robert Sumwalt said: "It is unfortunate that Tesla, by its actions, did not abide by the party agreement. While we understand the demand for information that parties face during an NTSB investigation, uncoordinated releases of incomplete information do not further transportation safety or serve the public interest."
On 23 March a Model X SUV hit the median strip of a road in the Californian city of Mountain View and flipped before being hit by oncoming vehicles. The male driver later succumbed to his injuries in hospital.
