Joystick Steering Wheel

How to use

 - Move the left joystick of your controller to the edge and move it towards the wheels facing direction ( The white dot with green and red dots beside it). 

 - When the wheel snaps to your joystick you can move it freely around until the max steering angle is reached. 

 - If you let go of the joystick the wheel will automatically center itself. Letting go of the joystick slowly will emulate the traction of hands slowly releasing the steering wheel.

Please give me your feedback. Do you think this could be practical? Would you use this for racing games (arcade or simulation) or driving simulators (e.g. ETS2)?

Info: Running the test in Firefox doesn't seem to work. Atleast not for me.
