Regulators said Comma AI devices struck slow-moving or stopped vehicles in their lanes. NHTSA had issued a broader warning to driverless-vehicle developers about emergency vehicles. A device that promises hands-off driving for cars people already own is under federal scrutiny. The National Highway Traffic Safety Administration opened a preliminary investigation on September 21 into devices made by Comma AI, the startup founded by security hacker George Hotz , who is no longer managing day-to-day operations but remains a major owner. Regulators said vehicles equipped with the devices struck slow-moving or stopped vehicles in their lanes.
