Nevada [has become] the first [state] to approve a license for autonomous vehicles" -- in other words, cars that cruise, twist and turn without the need for a driver -- on its roads. The license goes to Google. Engineer and Google X founder Sebastian Thrun said that the self-driving vehicle project aims "to help prevent traffic accidents, free up people's time and reduce carbon emissions by fundamentally changing car use." He noted that the "automated cars use video cameras, radio sensors and a laser range finder to 'see' other traffic, as well as detailed maps ... to navigate the road ahead." There is no driver needed, though one is typically in the front seat ready to take control if need be. Earlier this spring, Google said it had "safely completed over 200,000 miles of computer-led driving." Nevada issued a special license after demonstrations on state freeways, state highways, in Carson City neighborhoods and on Las Vegas' landmark Las Vegas Strip, the state's Department of Motor Vehicles said in a news release. All such cars on the road are "test" vehicles for now, though the state signaled it intends to be "at the forefront of autonomous vehicle development."
