I've been driving one of the slower cars available for a little less than a year now. And I've noticed (on county road) the speed you go is not limited by the car much, speed is limited to how fast you drive it. So owning a fast car is less relevant. Now I know a Prius could go fast, in terms of real road hooning, so has anybody done It on a regular basis? I would assume it has a fair balance because of the batteries.
