Linking cars into a trainlike group can save fuel, fit more cars on the road, and potentially improve safety. A project in Europe shows it's not just a fantasy.
Recent tests, says Lockheed Martin, show that fully autonomous convoys can safely navigate road intersections, oncoming traffic, stalled and passing vehicles, and pedestrians.
During the day, paths coated with Starpath absorb UV light, which is released when darkness falls. The technology could be a cheaper, more energy-efficient alternative to nighttime street lighting, its maker says.
Volvo's new motorway driving concept sees you joining a convoy where you're electronically tethered to the car in front. It sounds terrifying.
Why waste your drive time doing the actual driving, when technology can be your chauffeur? The century-old auto culture is on the verge of radical change, and you can thank Google for where it's headed.
Car computers will use many sources of data -- lasers, radar, stereo cameras, even windshield wiper rain detectors -- to figure out what's around them. And none of the sensors will ever get drowsy.
A new world beckons in which urban transit networks will be able to warn about road conditions or adjust road speeds to relieve traffic congestion.
