GM networks cars to help you drive, or do it for you

Because really, no one can be expected to drive their own car these days,
General Motors is working on a system to equip cars with GPS and
wireless networking so that they can communicate with neighboring vehicles and alert each other when they're getting too close, or if one of those moron human drivers is trying to merge without signaling. The system picks up on nearly 100 internal sensors inside each vehicle, such as engine speed,
braking, and that ever neglected turn signal, and transmits the info to other cars within a quarter mile radius. If you, or a neighboring vehicle, is about to do something dumb, the system can alert you by vibrating the side of your seat the danger is coming from, displaying a yellow or red light on the dashboard, or even hitting the brakes if doom is imminent. GM says this system is cheaper than the current systems being used in luxury cars that require distance sensing external sensors, but since it relies on information from the other cars on the road it will be a long while until there is the market penetration needed to make this useful. We're also skeptical how accurate a system based on GPS will be for detecting the difference between close and too close, but we're sure they'll figure something out in the five to 10 years before this goes into production.
