I agree with Felix above - no matter how powerful the car, speed limits should be observed.Plus some people buy supercars and havn`t got a clue how to handle them - I hit the curb yesterday avoiding a very powerful car who could not keep on his side of the road as he took a corner too fast - and that was on a suburban side road. The place for speed and fancy overtaking is on the track IMHO.
Grump over.
