Drink-drive detector radios police. A tiny fuel cell that detects alcoholic fumes in cars and calls the police is developed - automakers are very interested [New Scientist]

Texas Christian university researchers have developed a $100 USD detector that  can sense the presence of alcohol on a drivers breath. The sensor is mounted in the steering wheel or the sun visor so that is within 50 cm of the drivers mouth.

Some Questions:

• What is to keep the user from taping over the hole?
• Or opening the window to dilute the presence of alcohol in the air?
• What if I just took a hit of Listerine before going on a date? Now I'm going to get flagged for a DUI, especially given Law Enforcement's zero tolerance policies of late.
• The device only alerts police that the car is being driven by someone with alcohol on their breath, the police still have to pull them over. Ever seen World's Wildest Police Chases?

This could be a bad thing given it's potential for abuse and misuse, should it become commonplace.
