General Motors has taken WiFi to a whole new level. By allowing smart phones to communicate with one another, cars with the WiFi technology can detect pedestrians on the road, leading to a safer driving environment.

The obvious drawback, though, is that it requires a pedestrian to prepare themselves beforehand.
