I will have a look at your code tomorrow.
But I think, i have done a mistake, too, because the car only stops and does not roll back, after a crash (even when crashing a static wall). an yes i am updating velocity and position.
this is a bit strange, because everything else looks pretty good.

Update from the cylinder shape works better now.
Next week i will really give you a video
There are still problems with bouncy wheels and in consequence very hard hits by the ff-wheel. i also had to take the distance from the center of the wheel. when taking the distance from the wheel rotation axis, the car jumps and same for the depth of the hit.
I have also no idea, what the parameters in setcontact are for. the tread f.e. isn't even used and the road frequency thing also makes only problems.
