cartechboy writes "And you thought stealing cars was hard today? You're facing locks, kill switches, LoJacks, OnStar, and more. But there's worse on the way: Engineers at Japan's Tottori University have developed a prototype theft-prevention system that uses brain waves to identify drivers. That's right: The system samples your brain waves, stores them--and actually shuts down the car if the driver's EEG signals don't match what's on file. It also busts drunk and sleepy drivers, because their brain waves differ from those when you're fully awake and totally sober. One non-Tron downside: If you want to drive, you have to wear a scary-looking set of sensors on your skull so the car can constantly reads your brainwaves."
