GPS and Breathalyzer All in One

We don’t need to tell anyone that drinking and driving is not a good idea. A Portuguese GPS company’s latest handheld navigation unit not only tells you how to get where you’re going, it also tells you if you should even get behind the wheel; one of the settings is a breathalyzer.

You simply blow into a small sensor on the side of the unit and it tells you your blood alcohol level.
