Mount your smartphone in the dash of your car and it could join a network of smartphones that watch traffic lights and tell you how fast to drive to get to the next traffic light without wasting gas. Researchers from MIT and Princeton say the technology, called SignalGuru, helped drivers cut fuel consumption by 20% in tests done in Cambridge, Mass. The see-all cameras could also note fuel prices and available parking spaces or, who knows, who’s looking hot in lines outside crowded clubs.
