Autopilot supplier disowns Tesla for 'pushing the envelope on safety'

Mobileye says capability of system to do the driver's job was overstated but Elon Musk's company denies ever suggesting its cars could drive themselves

Mobileye broke ties with Tesla Motors because the Silicon Valley firm was "pushing the envelope in terms of safety" with the design of its Autopilot driver-assistance system, its chairman has said.

"It is not designed to cover all possible crash situations in a safe manner," said Amnon Shashua, who is also chief technology officer at the Israel-based maker of collision detection and driver assistance systems.
