Watch! Hold down the mouse and drag to scroll around (when not following a car) Click on a car to take control of it! Exit by clicking anywhere else. When controlling a car, use arrow keys. Need I say more? :3 Play with the sliders and watch how they affect the cars. ;)
Credit to RHY for 3D car sprite I got the turning script from my Waypoint AI, which I reconfigured for 3D! If the sprite doesn't appear on the track right, it's because the costume center is not really at the center. And there's 72 costumes.
