Re: the ultimate car physics Problem.

Yeah, as somitomi said, this is complicated to properly model. But in the case of simulated physics in a game, maaaybe you can get away by using 3 different friction coefficients: one for side slip, one for longitudinal slip (when braking), and one for regular longitudinal (when not braking). Then ...

No. It wouldn't be enough to have standard plumbing.

It has to know, for example, how to move all of the cleaning supplies you have under the sink. ...
