Anyone here have a simple car tutorial with Bullet?

[Mars_999]

I am trying to learn some Physics lib, and as of now I am not sure which one to go with. Bullet, PhysX, Newton. I want X-Platform, and free to use. What I also want is someone who is able to answer questions... I see this is lacking on some of the other Libs forums.

So my first question is anyone have a simple tutorial using Bullet with a car that has 4 wheels and uses .3ds files? Maybe I should try the simple 4 cylinders and a box first?

Now, for terrain, with the vehicle demo can I just dump my vertices and indices I have already calculated, and send them to bullet instead of the data the demo sends? Meaning is that all there is to getting Bullet to work with a terrain mesh?

Thanks,
Any help would be greatly appreciated.
