I rode in a self-driving Uber, and I'm glad there was a real driver as backup

A handful of people who order Ubers in Pittsburgh this morning will discover that their driver is less chatty than usual. And like those lucky riders, I got to experience being chauffeured around town in one of the company's experimental self-driving cars. I also got to sit behind the wheel and try driving--or, rather, supervising--one of Uber's new vehicles. "We're going to slowly start inviting our most loyal Pittsburgh riders to experience the future," says Raffi Krikorian, director of the Uber Advanced Technology Center in Pittsburgh. "If they call for a ride, then a self-driving Uber might turn up."
