Window Waver
Are you a calm driver, who enjoys a gentle cruise down country roads, taking the scenic route at all times to take in the peaceful view? Or, ARE YOU STRESSED? Do you suffer from ROAD RAGE? Shouldn't you be warning people about your outrageous, mobile mood swings rather than bursting out in irrational rage? You could try warning unsuspecting road users of your ferocious temper with the Window Waver. This Warning sign, reading "DANGER of Road Rage", sticks to your car window and the little stressed- ut guy waves from side to sider in time with the motion of your car.
Maybe he can tear his hair out and you can leave yours alone? You wouldn't want to aggravate that receding hairline now, would you?
