WALTHAM, Mass. — An alcohol-detection prototype that uses automatic sensors to instantly gauge a driver’s fitness to be on the road has the potential to save thousands of lives, but could be as long as a decade away from everyday use in cars, federal officials and researchers said Friday.
U.S. Transportation Secretary Ray LaHood visited QinetiQ North America, a Waltham, Mass.-based research and development facility, for the first public demonstration of systems that could measure whether a motorist has a blood alcohol content at or above the legal limit of .08 and – if so – prevent the vehicle from starting.  MORE
