Vehicular ad-hoc networks (VANET)
It has to be 4 or 5 years ago when I heard Audi and BMW working separate but similar VANET projects outfitting their vehicles with black boxes, sensors, and wireless LAN. Ultimately these were for proprietary ad-hoc wireless networks. Your Audi or BMW would communicate with other passing vehicles about the traffic flow, accidents or delays, etc. enabling for intelligent GPS decision-making.
Now considering the realistic driving conditions (i.e., actual speeds) of these cars, you have to wonder if WLAN with b/g radios can muster to catch up. I mean, stationary vehicles sitting momentarily at a traffic light is viable but how often do cars travel in-sight or within the speed limit? IMHO WiBro would better fit the bill for this application.
Anyway a group of UCLA engineers are working on their own flavor of VANET.
