Then again, one could put pc to car and also get nice future display that makes windscreen to your display device, I saw ad of such thing somewhere, Any glass surface is ok, some foil it was.
Harder would be to make pedals and steering to disconnect from steering rack and throttle linkage easily so that you could turn switch or something like that to connect them back when you are really driving somewhere. Clutch and brake don't need to be disconnected, those would just make more real feeling, some guys have build pedals and used some master cylinder to add realistic feeling to it
