Having driven nearly three million miles in trials, Google spin-off Waymo is ready to begin real-world tests of its autonomous vehicle tech with members of the public; the company is now offering free rides to people in Phoenix, Arizona who want to participate in its Early Rider program. If you’re in the city and travel around the Phoenix metropolitan area – including the towns of Chandler, Tempe, Mesa and Gilbert – you can sign up by filling out a form on Waymo’s site.
