Robotic Cars
Tiny, battery-powered cars called EN-Vs, now in R&D, can talk to each other, come when called, even drive themselves.
Will the car of the future be able to drive itself? At the GM Tech Center, engineers are testing two-wheeled, battery-powered cars called EN-Vs. About five feet long and weighing under 1,100 pounds, the tiny cars don't use up much energy or space. And they're smart: With GPS, the EN-Vs can plan a route to their destination and even talk to each other.
