Since most of the car is electronically controlled, would it be possible in the future, to use it as a car simulator? Either playing a car game on the 17" using the steering wheel and pedals to control the car? It could also be via the API on a projector on my garage wall...
Why not just replace the windshield with a big LCD screen. With external cameras, you can drive in the real world using the screen, and then Alt+Tab back to the game while driving. Best to keep a real-world window open though rather than minimizing it. This is the future of driving. Eventually all control will be from the screen. For example, R-Click main video window>Settings>Lights>Turn Signal>Right.
One problem is that the steering wheel is physically linked to the wheels, so while it may be possible to read the position, you would actually be turning the real wheels as you play the game. (The brakes are also physically linked to the brake pedal.)
A bit of a tangent here, but I hope that GTA V has an EV clearly inspired by a P85 (GTA games do not feature licensed vehicles, for a number of reasons).
