"it appears that if the code had a way to predict the difference between it just oscilating up and down fast versus it really leaving the ground for more than a couple millisecs that the perfomance of the wheel slip routine really starts to look good."
Hm...
That may be so, but I don't like the idea of averaging things over several frames to dtermine the outcome. I would prefer to find a solution which involves forcing the tires to stay on the ground with springs.
Maybe the solution is to use two springs. A short squishy spring to simulate the rubber of the tire, and a stiffer longer spring to simulate the shocks. The squishy spring would compress easily, and would expand quickly, keeping the tire ont he ground longer when the car lifts off the ground. The stiffer srping would allow a lot more motion, but respond more slowly to changes.
