Perfect Driving Simulator

I don't drive much anymore. I don't need to. I have a bike, almost everything is close enough to use it, and it costs me two dollars every time I move my car. The bonus is that my roommate pays for monthly parking, so the more he moves his car the more he feels like he's getting his money's worth.

The problem is that I don't get the thrill of driving anymore. I don't get to feel the rush of speed and control of a vehicle. I do still have my copy of Gran Tourismo 4 and wheel, but my good setup from before is spending time under my computer screen, so I'm less motivated to play when I need to use a less-than-optimal setup. Now, if I could build one of these I would be set. Where would I put it when I wasn't using it? Those questions are best saved for times when actual building is a possibility, instead of a pipe dream.
