1) Great idea, didn't think of that. I'll give it a go. I'm actually using the steering code from the JV-ODE demo, with some tweaked values. I can't figure out why this problem doesn't happen there.
2)The situation of one wheel being off the ground and another on the ground doesn't occur often, and isn't as much of an issue as the first point, and it doesn't affect the handling of the car much, but it does look odd sometimes during tight turns if the one side of the car lifts a little allowing one wheel to spin up to max speed while the one on the other side drievs the car forward at the usual speed.
Thanks for your help, KuRi, I'll have a stab at implementing your solution to 1) tonight!
