Problem is, most of those systems depend on vehicles going it alone, using radar and other technology to avoid hazards in their way. But what if cars could talk to one another and the surrounding infrastructure? Wouldn't that be even better — and safer? The US Department of Transportation thinks so, and it's hoping to prove it in a new series of 'talking car' experiments taking place in six locales across the US. These technologies may potentially address up to 82 percent of crash scenarios with unimpaired drivers, preventing tens of thousands of vehicle crashes every year (further research [PDF] will incorporate heavy vehicle crashes including buses, motor carriers, and rail)."
