Ingame physics engine, how good is it?

[Zartax]

As the topic states, I'm curious about how good the ingame physics engine is. Skidding and sliding is a very real part of driving a vehicle and add grealty to the realism and fun when in one. So does rolling, doing 180/360 and other fung stuff too. In many FPS games the vehicles are handled in a simpler way, since they are not the in focus as much as the single soldier. Even in games with much focus the vehicles are handled in a very simple way (the jeeps in Battlefield 1942).

I really hope that the vehicle physics are as good, or nearly as good as in Halo, where you can do anything with your vehicles, and it looks and feels real.
