There have already been a couple of different devices developed to keep people awake while they're driving, but one more can't hurt, right?

This new sleep-detecting car seat from Japan is a step up from previous devices in that it uses physiological data to determine someone's drowsiness rather than merely the angle of their head. It can read one's pulse and respiration, looking for signs of someone getting ready to drift off. The only problem with the seat is that while it can tell when you're about to fall asleep, it still can't do anything about it. As soon as they put in some sort of alarm or something that slaps you in the face to wake you up, look for this to appear in cars, probably within five years. — Adam Frucci
