This is a system that hooks up to your Xbox 360, I just found out last night and I am still researching.
Heres a few videos, you will be blown away.

At about 40 seconds into the first video the girl is playing a racing game. Keep watching and she uses a clutch, brake and gas to control the car as well as a shifter.
