Google Puts Cute Little Rides on the Road

Google this week unveiled a prototype that it will test on California roads to learn more about how to make safe and efficient autonomous cars a mainstream reality. For about four years, Google has been developing self-driving technology that could make the roads safer, and its newly revealed prototype is the latest step in the project. The tiny vehicle is reminiscent of a Smart car, except for the sensors on top. They're designed to eliminate blind spots and provide a view of more than the length of two football fields in all directions.
