Apple Might Be Leasing Chrysler's Old Proving Grounds To Test Autonomous Car Technology

"If Apple’s indeed working out of the former Chrysler proving grounds, then the Phoenix area is quickly becoming a hub for work in the self-driving car space, said Bryant Walker Smith, an assistant law professor at the University of South Carolina who focuses on autonomous driving. 

A “big but convenient” space is necessary for Apple to try out things it’s not ready to share publicly—automotive or otherwise, said Walker Smith, the professor. With the former Chrysler Proving Grounds in Surprise, the company would have an ideal environment for testing autonomous cars, he said."
