Sooner or later, most drivers will make a mistake that could lead to an accident. Driver error is a common cause of car wrecks. Drivers can be distracted, exhausted, irritated or confused at exactly the wrong moment, leading to a serious crash. Eliminating driver error would drastically reduce the number of auto accidents that occur every year on American roads. The National Transportation Safety Board is hoping that connected-vehicle technology can help. Cars that communicate with one another, with the road, and with drivers may prevent thousands of accidents every year.
