Recently I was at a really funny race. Some guys tinkered from a beer crate a racing machine. Equipped with a motor, but according to rules came here with no brakes real racing beer crates on the street. Some racers were equipped with about 30 horsepowers, bringing it about speed to 100 km / h. Even a delirium of speed, then someone who just can slow down with the shoes.
But for the audience it was an exciting race. I can only recommend to visit such a race if you have the chance.
