10 silly car gadgets you won't believe
How's your driving? Read my sign
Giving mean looks to the guy who almost sideswiped you may be satisfying, but you can never really tell whether they saw you or not. Solve this problem with the Drivemocion Car LED sign, which uses light-emitting-diode technology.
Attached to rear windows with suction cups, these gadgets can display one of five animated facial expressions through the rear windows of cars. A remote-control unit can be used to switch between the various faces.
Not the aggressive type? No worries. The sign also can deliver friendly messages of praise to other drivers with a smiley face or even make the first romantic move with a "flirty face."
