Given the nature of driving, the only position suitable for using this wheel is in the sitting position. The bottom of the base is contoured to fit your legs, and the addition of retractable leg supports on either side keeps the unit snug on your lap. A gas and brake unit is included, and attaches to the main unit with a detachable cord.
The Wheel unit is adorned with every button found on the regular controller, including the d-pad and two butterfly pedals behind the wheel that you can use if you don't like the foot pedals. All of the buttons are analog, so theoretically you could use this wheel with any XBox title.
