PolygamousRanchKid writes "Ford says its new Fusion, which will debut at the North American International Auto Show in a couple weeks, will be the first mainstream midsize sedan in North America to offer a lane departure system. Lane departure systems are aimed at warning drivers, especially drowsy ones, if their vehicles wander out of their lane. A digital camera mounted on the windshield ahead of the rear-view mirror keeps a watch. The system not only causes the steering wheel to vibrate if it senses an unintentional lane departure, it will also steer the car back into the right lane. The National Highway Traffic Safety Administration estimates that 100,000 police-reported crashes occur every year as a result of drowsy drivers, leading to 1,500 deaths, 71,000 injuries and $12.5 billion in monetary losses." I'd just like to know how hard the AI will fight if it misinterprets a driver's intentional lane change.
