This is the Drive Alert Master, a diminutive way to stay awake in the car on those special highway jaunts when consciousness is priority No. 1. The DAM will sound a piercing beep at the "first sound of drowsiness," which we have to assume constitutes any cranial movement of 2 inches or more. Feel at total ease on your next cross-country venture as your earpiece blasts arbitrary alarm after arbitrary alarm through your head, steadying your nerves and your hand. Shit-eating grin optional.
