Drive Alert aims to keep drivers… uh, alert

The Drive Alert Master's goal is to keep weary motorists from falling asleep at the wheel. You set the wake-up angle (options are 15° or 30°) and wear it behind your ear. Then, should you begin to doze off, a loud beeping sound will rush you to attention once your head starts to tilt. Supposedly, "It's popular with truck drivers." As handy as the Drive Alert Master might be, if it ever goes off while you're driving, make sure you take a pit stop and rest rather than continuing to rely on a $16 gadget to keep from dozing. Oh, and dance instructors — now you have the perfect way to keep your students from looking at their feet.
