Vehicle scripting and/or vehicle model problem

Right. So this is my first time trying to make an actual vehicle, and this is what happens.

I have no idea what the problem is. Also, how do you change the position of the seat?

Apparently you have to remove the wheels before you make a collision model. oops. I also rotated the model -90 degrees so that it would face the right direction, but now the playermodel sits sideways. How do you change the position of the seat? I tried decompiling other vehicles but I have no idea what to look for.

Well, I got it working. It handles like a walrus sliding on ice, and, as I mentioned in the first post, the playermodel sits sideways.

I can’t find any documentation for vehicle scripts at all, so I need help with this.
