If there was any doubt left that Tesla is serious about self-driving car tech, it all but disappeared this week. The company has confirmed to Electrek that it recently hired processor design veteran Jim Keller to lead its Autopilot hardware engineering team. He's not only responsible for some of AMD's key architectures (such as the Athlon K7 and the upcoming Zen), but helped make Apple's A4 and A5 chips -- you know, the ones that powered everything from the original iPad through to the Apple TV.
