DC shows off new car-to-car communication system

Automation is quickly starting to flood automobiles these days and DaimlerChrysler is putting the finishing touches on a system that could make traveling roads safer for drivers around the world. DC's Wireless Local Danger Warning (Willwarn) joins the likes of self-steering, automated parking, radar-based cruise control, radar-based rear collision detection and traffic/weather-enabled GPS systems.

Willwarn uses onboard ABS, ESP, EBD and GPS systems to monitor hazardous road conditions (fog, black ice, pot holes, etc.) or broken down vehicles. The data accumulated is then transmitted via an ad-hoc WiFi connection to following or oncoming vehicles within a 500 meter radius. Cars near the edge of the 500 meter radius of a signaling vehicle can also become a beacon to relay data to more vehicles.

The information collected is then displayed to the driver so that proper precautions can be taken to avoid or safely navigate problem areas on the road.

DaimlerChrysler hopes to have the new system in place by the end of the decade with high-end Mercedes and Maybach models most likely getting first dibs.

Why would we give them credit? It's just another feature that can go wrong. If they can't even manage to make door handle springs that last long term, don't pretend you can assume something far more sophisticated will turn out ok.

As another poster already mentioned, even existing semi-matured wifi technology is flawed, it would be rather unfounded to think they will get a new technology right on the first try.

As for the worst that can happen it depends on how it's tied into the other systems. Might be possible to lock up the dash display. Might constantly generate fake warnings so the driver starts ignoring warnings, only to encounter a legitimate warning they ignored out of the false sense of security the system had previously given them.

What else could happen will depend on not just the vulnerability but the inventiveness of the attacker. Even mildly disorienting a driver could be used in a type of fender-bender-and-rob scheme.
