I don't know if this is useful or not but the car tutorial on Unity 3D
http://unity3d.com/support/resources/tut...r-tutorial has plenty of interesting bits in it.
A lot of code used in Advanced Physics scene with Lamborghini seems to have similarity with Vdrift (or is there a further common root?) There are almost no comments.
I am only interested in tyre model, so looked only at Wheel and total forces calcs.
Looks like somebody got slightly confused there. E.g. they use a[0]..a[14] array with lateral slip coefficients but fail to notice that presence of a111 and a112 causes a12 and a13 to be repositioned into a[13] and a[14]. So code ends up declaring a[0]..a[14] but uses only a[0]..a[13] in calculations.
Hmmm...
