Driverless Car to Hit California Roads
Who says a car needs a driver? California Gov. Jerry Brown signed a law on Tuesday that makes it legal for driverless cars to travel on state highways. This opens California roads to the cars -- an important step for testing.
PBS NewsHour correspondent Spencer Michels reports on the story and a demonstration near San Francisco by one of Google's test cars. In it, the director of a local center for the blind pilots the car -- and survives.
More on the groups that oppose the vehicles and the mechanics of how they work in the video above.
