Tire model woes
My recent experimentation with stability control has exposed an issue with current tire model. The used force combining method (beckman) seems to be wrong, not sure whether it is the implementation or the method itself.

I've noticed the behavior before to some degree(with F1-02 and karts) but never looked into it. With the stability control where wheel brakes are engaged independently the problem is quite noticeable.

Beckman combining as we have it favors heavily the longitudinal friction, to the degree that the total force is acting against the expected direction. I think we will have to fall back to no combining, or go with one of the simpler combining methods.

beckman: braking with steering to the left, longitudinal braking force rotates the car to the right against the expected direction
