Stupid Dangerous Vehicles

Its been a while since I've spotted a stupid vehicle thats guaranteed to cause a wide variety of injuries. But now a new contender has entered the fray, the Rollercycle. Its a stupid name for an even stupidier product. A tiny petrol engine is attached to a wheel and you basically strap this thing to your ass while rollerblading so you can go faster. Pure genius I say, for one its sure to make you super unstable meanwhile while increasing your speed. I'm just waiting for all the reports of broken arms and legs.
