For the control, just use car behavior and just set the steer speed and possibly drift very high. For the background, there are three main layers. 1: The main game layer; 2: The asteroids layer; 3: The background layer. The background layer will have a parallax of 10-20%; the asteroids layer will have 30-50%, and the main layer will have 100%. You can play around with the parallaxes to get them how you like them.
