Yeah, It doesnt looks realistic. And also, it doesnt have much grip.

I made a mistake in the track modelling. I tryed to make the center of the track a little higher then the part closer to the grass.

This is making the physics react strange.
When the car goes into the turns, and even in the straight part, It changes direction a lot.

Only for fun, I will model another track, completely flat from side to side, to see what happens.

I Think the next step will be what Ventilator said : c-lite for the movement, physics for the collisions.

If I could manage the speed, turns and skkiding with Lite-c and, the PhysX for the collisions, I would get something nice.

I have a nice car behaviour wrote in c-script that I can port to c-lite easily.

My dount is : I know that we cant c_move a physics active object. Apart of this, I think... when the car collide with something, or another car... what could happen ? How to manage it ? Any ideas ?

Questions, too much questions.
