Night vision systems in cars would seem to be of limited use since most roads are well lit and, besides, other cars have lights on them, too. But pedestrians don't, and that's where BMW's system proves its worth. Infrared cameras scan the road ahead and computers that are programmed to recognize human shapes point out pedestrians in or near the road.
The system not only recognizes people ahead. It also indicates what direction they're heading. If people to the side of road are facing as if they're about to step into your path, the car will alert you.
