New car system may prevent drunk driving

LOS ANGELES The systems would be invisible and would include breath analyzers built into the steering wheel that can sense alcohol on a driver's breath. Touch sensors are also being developed on the car's starter button that can detect alcohol levels in the skin.

If a driver was legally drunk, they wouldn't be able to start their car. Engineers say the new technology is a life saver.

The government and automakers hope one day to have these devices in every car, but the restaurant industry worries that customers may have just one drink with dinner and be unable to start their cars.
