Just to go back and talk about the scheduler question, VDrift doesn't have a scheduler but it has a few different rates that it will run things at. All of the physics run at a fixed time step, and some of them run at higher rates than others. For example, the chassis is simulated at a rate around 100 Hz, but the wheels/tires are simulated at around 600 Hz (NaN knows the exact rates). The graphical display is updated as fast as the card can draw it, which is variable, and independent of the physics rate. The graphics will just grab the latest physics results and display them on the screen.

The pacejka equation is pretty fast, I don't think there's a need to precompute it (although I haven't had a chance to profile the latest trunk).

Motion blur is an eye candy effect that isn't enabled at the moment. The approach I like is a rough approximation that's purely there to make things look cool.
