NHTSA asks 12 automakers for help as it investigates Tesla crashes
It wants to compare Autopilot functionality and crashes against other OEMs' systems

The federal government's automotive safety watchdog has taken the unusual step of asking 12 major automakers to assist its investigation into a series of crashes in which Tesla vehicles have struck parked police cars and fire trucks while Tesla's driver assistance systems were activated.
The National Highway Traffic Safety Administration (NHTSA) said it has written General Motors, Toyota, Ford, Volkswagen and others because it wants to perform a "comparative analysis" of Tesla's systems against other "production vehicles equipped with the ability to control both steering and braking/accelerating simultaneously under some circumstances."
