This is the latest boy racer craze at Cheddar Gorge. Downhill freewheel racing on trikes in the face of oncoming traffic. Racing on the highway is already against the law but as BH says, where is the enforcement? There are lots of videos of this on youtube and in some the racers are waving at the police as they flash by them.
