Awesome graphics! And I love that big screen on the wall where you get a top view of the race! And the controls are spot on, leaving you lacking a bit of control but just enough so that it isn't too frustrating. The leader board is an awesome feature.
Would love to see what you can get working with the AI, I found it pretty funny to see them struggling around the track when I tried that out. I wonder if you continued with this, it could take a turn in some unexpected direction a la GTA... :P
