It is an unspoken and logical rule that one ought not take to the wheel whenever one is sleepy, but somehow or rather most people think that sleep is not a biological function but more a matter of willpower - and they learn this through disastrous results. The Anti-drowsy Alarm aims to help prevent drivers from dozing away, as it has a sensor that can detect whenever your head nods below a preset angle, kicking in a screeching alarm. I wonder how effective this is - someone who nods off only to be rudely awakened by an alarm might actually turn the steering wheel the wrong way out of shock. Well, I guess it can also be applied for other purposes, especially students who love catching a nap right behind the class. The Anti-drowsy Alarm will retail for $10 each.
