I'm not for banning such vehicles. However I do thoroughly believe if you cause an accident and illegal an excessive speed is a contributing factor then you have just sacrificed your right to drive. Because clearly you are an idiot and can't control a car as well as you think.
I also have the same attitude to drink drivers, if you are caught driving dangerously, pissed out of your tree, you should loose yer license.
If you take a high performance car or bike to track and let loose. Fair play, but you're on a track with others who accept the obvious risk. However if you come round a corner enjoying yourself and hammer into me at 100mph as I'm out on a sunday driving along with my wife and kid. It IS YOUR fault and I don't care what driving skills you think you have. If I happen to survive it I don't think you should be on the road.
