It's built into the dashboard of your vehicle and will talk to you, tell you jokes, and monitor your responses ... why? To keep you from falling asleep at the wheel,and adding yourself to the 30% of road traffic accidents caused by falling asleep at the wheel. Some of the countermeasures are entertaining, but there's no mention of electrocution. Damn!"
