Saab is working on a key-fob breathalyzer, integrated into the ignition, which will prevent drivers who are over the legal blood-alcohol limit from starting their cars. The Alcokey (Alkey?) comes with a tube into which drivers must blow to get a readout letting them know if they are legally permitted to drive. Why stop at cars? There may be a market for a personal device to prevent beergoggles incidents, if you catch our drift.
