No More Drunk Driving

An engineer from Nissan demonstrates a concept car designed to prevent drunk driving and falling asleep at the wheel, which has a facial recognition system to monitor the driver's eyes for detecting signs of drowsiness, during the company's advanced technology seminar in Tokyo on February 21, 2008. The system also has a special gear stick knob with a highly sensitive odor sensor to detect alcohol in the perspiration on a driver's palm. Photo: AFP
