Nissan shows safety technology that helps avoid collisions

In a bid to make its cars even safer, Nissan will soon fit its cars with a gas pedal that lifts to warn of possible collisions, at the same time the car will automatically stop if driver takes his foot off the accelerator in response to the warning. The technology used combines radar sensors and a computer system that gauges the car's speed and the distance to a vehicle in front. Cars with the new safety features will be available this year in Japan, and next year in the U.S. Another experimental system showed off by the company hopes to tackle dunk driving, which causes more than 600 fatal accidents-a-year in Japan. They have developed a system that measures alcohol levels in a driver's sweat from sensors in the gearshift. The system almost locks down the ignition and issues an electronic warning.
