about claiming that you know more than about high speed driving than anyone here, umm I have driven on the autobahns in Germany - you will be tootling around at 250 km/h and you see a couple of lights flashing in the rear view, a few seconds later you see a car pass you at 300 km/h.
Its not all about speed, driving at those speeds demands a great deal from both the machine and the driver, one sneeze at those speeds and you are a burger patty.
