In a potential bid to corner the celebrity market, Nissan is developing an in car Breathalyzer. In equipped cars, the system is activated when the key is switched to "on," requiring the driver to blow into it before the engine will start. If the blood alcohol level is determined to be above a preset limit, it disables the vehicle's ignition. No word on what Nissan's plans for the system are or how long the vehicle would remain disabled, so keep it away from your hilarious drunken friends.
