Have you ever wondered how cool it would be to have a breathalyzer integrated in your iPod’s FM transmitter? Neither have we, but David Steele, creator of the iBreath (what else did you expect it to be called?) claims it’ll be one of the hottest selling products of this holiday season.

To use the BAC, you simply fold out the straw and exhale into it for a full 5 seconds. Five seconds later you know whether it’s safe to drive home or you need to call a cab. The FM transmitter allows you to manually adjust the frequency being broadcast, and this is displayed on the LCD display.

At around $80, it’s twice as much as a standard FM transmitter, but we think the functionality is worth the extra moolah.

You can buy one from here.
