[ODE] problems with hinge2 & car steering

[Sergio Valverde]

Well,finally I realize that the wheel-terrain contact was
so "sharp" that precluded the car to steer "correctly"...

You were right Chris, the friction was very high. I tested
the model with lower friction coefficients and I got better
results. 

In fact, I think it's better to use the Slip1 & Slip2
coefficients to model sliding & skidding effects than
to reduce the friction coefficient.

What do you think?
Sergi

what is the friction in the wheel contact with the ground? If it is too high
(or dInfinity) you will get these problems
