Fuel cell system could help nab drunk drivers EETimes.com 9 Sep 2001

An engineering team at the Fort Worth, Texas, school has developed an electronic technique that enables policemen to identify drunk drivers among passing motorists remotely. The technique not only provides probable cause for law enforcement agents to pull over impaired drivers, it also gives society a means to deal with an epidemic that kills thousands of people every year. The technology is also expected to be well-received by automakers concerned over liability claims caused by drunk-driving accidents.

A technology even more invasive than the flashlight breathalizer. And they have the daring to claim this can be used as 'probable cause' for a stop and search.
