US investigation after fatal Tesla 'Autopilot' crash

The US government has launched an investigation into the safety of automaker Tesla's autonomous driving system after what may be the world's first known death involving "self-driving" technology. A driver of a Tesla Model S car operating the system, which is called Autopilot, was killed in a collision with a truck two months ago, prompting the probe, which was disclosed on Thursday. The investigation comes as Tesla and other automakers are gearing up to offer systems that allow vehicles to drive themselves under certain conditions across a wide range of vehicles over the next few years. The National Highway Traffic Safety Administration (NHTSA) said it was now investigating 25,000 Model S sedans that were equipped with Autopilot. The accident, according to a report from the Florida Highway Patrol, killed Joshua Brown on a clear, dry roadway on May 7 in the state of Florida.
