hi all!
I wrote here 'cause I wish update this thing....
I explain my sensation: when I drive in a long turn, for example to drive in 3rd or 4th, the car seems that rotate around the center of the car, doesn't show the front tires, but seems that (example, turn in right) that the front tires turns right, but the rear tires turns left...
I don't know if I'm explained well and if is a sensation or is real this.
In general the behavior will depend on the car configuration(mass distribution, suspension, aerodynamics).
You can examine the simulation state by running "vdrift -debug". The interesting bits are the tire forces and the aerodynamic forces, torques as they determine the motion.
Btw you can record the run when you think that the car is behaving incorrectly and upload it. On windows replays are stored in "C:\Users\<username>\My Documents\My Games\VDrift\replays".
