Maybe because it's easier and safer to go in a straight line. I love my car for the twisty bits (probably more than the outright power) but there's so little opportunity to use it in this situation. Whenever I go to up to Sheffield to see my family, I also make a point of driving into Derbyshire because the roads (and the views) are fantastic in the Peak District. I do feel the Supra is a little wasted in Cambridge.
Also, when it comes down to it, the Supra is big, heavy car. If we totally went for handling over power, then we'd be a Lotus Elise forum
