Google's self-driving cars have been around for a while, but it's still totally surreal when you see one in everyday use. The search giant released this video of Steve Mahan, who is the first ordinary person to benefit from one of the vehicles. Mahan has lost 95 percent of his vision, but with the help of the self-driving car he's able to go out and run errands like anyone else. Watch as he orders tacos from a drive-thru window and picks up his dry cleaningâ€” all while being driven by an artificially intelligent Prius. "This is some of the best driving I've ever done," he jokes.
