Drive up and down the country all the time? Fall asleep behind the wheel occasionally and would enjoy not running people over any longer? Then, my friend, $20 will get you the “Drive Alert Master”, which should solve your problem, while also giving you a heart attack.

Slap this behind your ear, turn it on, adjust the wake up angle switch and then no matter what you do, don’t look down. It detects when your head slumps forward and when this happens, it’ll emit a loud siren to wake you up.
