[ODE] Simples Car Possible (for traffic)

[kurimail]

Thanks for all your answer. I have decided to use the simplest car i can
imagine. It is an only body, with 6 geoms:

- 2 boxes for the chassis
- 4 spheres for the wheels

all stick together.

then i apply forces and torque to make it drive.

at slow speeds the solution is good, i can have lot of traffic with no
slow down. although the cars behave like statues, hehe, but it is only for
traffic.

Cheers, KuRi!
