An anonymous reader writes: Could cars talk to each other wirelessly to avoid collisions? It’s been talked about for years, but thanks to advances in location tech, security software, and wireless standards, some real progress is being made. The U.S. Department of Transportation (DOT) is funding a $15 million project at the University of Michigan to test the nation’s first wireless network for auto safety. The 3,000-car study will equip vehicles with radio devices that will signal to drivers when there’s an imminent threat from another networked car. The concept raises privacy and security issues, but if all goes well, the DOT is expected to mandate that all new U.S. cars be networked with the technology. In which case, wireless safety legislation could be this generation’s version of seat belt laws.
