A bunch of students at the University of Navarre in Spain have come up with a gadget to help stop drivers from
falling asleep and causing accidents. The thing consists of a special cap with magentic field sensors that monitors
your brainwaves while you're driving, and then wirelessly send that data to a PDA which analyzes the brainwaves to see
whether they match those of a person who is awake or asleep and triggers an alarm if it looks like they're falling
asleep. Estimated price? 4,500 euros, or about 4,270 euros more than it costs to buy one of those basic driver alarm
devices which automatically sound if you start nodding off (though by the time your head tilts down, it might already
be too late). Also, you have to wear that special cap, something which might mess up your hair or make you look
somewhat less cool while driving.
