Nevada Is the First State to Approve Self-Driving Cars

While Google has been testing autonomous cars for years now, no state has allowed cars to legally roam free without a driver at the wheel. That's just changed: Nevada now allows self-driving cars on its roads.

According to PC Mag, autonomous test vehicles will display a red license plate, as opposed to the state's usual bluish-gray. When the time comes for consumers to have their own self-driving cars, they'll come with green license plates.
