LG 410 sports car phone, with built-in alcohol tester

So we noted the launch of LG's 410 series phone which is most notable for its sportscar-shaped design — but what apparently didn't get promoted when it rolled out last month is the fact that it includes a built-in alcohol test sensor. We heard about Siemens working on a
breathalyzer cellphone, but they either got too soused during the testing phase to actually get it to market or they gave up — and LG has picked up the slack, it seems, since they're claiming this is the world's first. It does make sense to pair the alcohol sensor with a car-shaped phone for that momma-told-you-not-to-drink-'n'-drive sort of vibe, but will it also prove effective against
drunk dialing?
