Challenge three of your friends to a remote control bumper car battle. You can move forward, backwards, sideways – get hit 25 times and your car is immobilized. Each car has front, back and side sensors. Battling Bumper Cars is a great portable game to take on the go! It comes with four cars, four transmitters and an inflatable bumping ring. You’ll need 12 AA batteries. The game retails for $45.
