Ever wish you could do something to get the idiot behind you from riding on your tail down the highway? Over in England, Colin Fruze developed a way to keep drivers away. He built a flamethrower into the tail of his motor scooter. Trust me, you don't want to follow this guy too closely.
The flamethrower was initially installed on his BMX bike, but now it's activated with the touch of a button from Fruze's scooter. The flames will blast out 12 feet behind the vehicle. Fortunately for everyone, this contraption is completely illegal. Although, there are many times I wish I had a similar setup.
