You know what's better than one self-driving car on the road? Vehicle-to-vehicle (V2V) communication isn't anything new, of course, but researchers at Switzerland's federal institute of technology, EPFL, are taking things one step further. By wirelessly connecting the LIDAR, sensors and navigation systems of two cars in convoy, both can get a fuller picture of the world around them. Put simply, if two autonomous vehicles are driving down a road, then all they can "see" is the data from their own systems. But if you can connect your car, say, to the one immediately behind you, then both systems get a wider field of view and better situational awareness.
