Really cool idea. Only, there's no way I could sensibly use my car's steering wheel to control a game without having the engine running for the power steering... I couldn't make it out in the video, but wouldn't this also wear out the tires in less than no time (due to friction with the ground)?

Potentially would make flat spots in the tire but I really doubt that they're going to play this much.

A number of cars are starting to appear with electric steering, bmw and mercs mostly. Maybe there is some way do turn off the linkage?

Not an expert here.Either way this would make waiting for your passengers so much more enjoyable!!

> We ended up solving the problem by not continously pushing the button down when turning. The further the wheel is turned to the left or right, the greater amount of time the button stays down and the further the car turns.

I'm a little confused at this statement. Does this mean they just had it tapping 'left' or 'right' instead of holding the button down initially?

I think the other way around. If I understand, it started holding the button, which oversteered. That didn't map onto tapping correctly, so that made a little snippet of code to tap.

I interpreted it to mean they used pulse-width modulation, varying the % of time the button was being pressed in relationship to how far the wheel was turned. It's the same trick used to control LED brightness, even though the light only has binary ON and OFF states.
