Using Brain Waves Can Shorten Braking Distance 90
cheros writes "A BBC article reports on work at the Berlin Institute of technology where brainwaves are used to trigger brakes. Apparently this cuts braking distance by more than 3m (10ft), but I have reservations about skull electrodes in any circumstances. I'll stick with radar, thanks."

Seems like way too much potential for false alarm - what happens when I'm driving along and thinking "Crap, I forgot to STOP for milk" or I see someone across the street about to get hit by a car and I think "That car's going to hit him, he better STOP! And my mind goes through the thought process of applying the brakes even though I don't do so"
I bet they can get nearly the same result by using motion sensors to detect the motion of the driver's foot off the gas pedal and over to the brakes - as soon as it sees the driver let up on the gas, it can prime the brakes and get ready for a panic stop based on the driver's next move - maybe instead of saving 12 feet of stopping distance they can only save 6 feet, but in a panic stop from 65mph, 6 feet (or even 12 feet) is rarely the different between a safe stop and an injury collision.
But an unexpected panic stop at 65mph with a 40 ton 18 wheeler right behind you could be fatal - even if he has this magic thought-control system, the laws of physics guarantee that your small car will stop faster than his heavy truck.

Your mind does not go through the process of applying the brakes without your actually doing so. It's not like your muscles have minds of their own and think "oh, that silly brain! he's just messing with me!" Your conscious mind may consider sending the signals, but the signals are not actually sent - if they are, then your muscles would move.
Your brain either sends the signal to the muscles or it does not. That's the signal they should be looking for.
