Yeah the collision between multiple vehicles was bugged - there are posts about it on the Newton forums, but basically the collision detection info for the vehicle was stored in the same skill as the top speed or some other variable. Changing the skill number fixes the problem (its skill8 if memory serves me correctly, so change it to like 18 or something).

The road system was kept simple because this will be used to teach a class to teens about 3D Game Design, so all of the road pieces are modular.

I'm just worried because the machines they will be using will most likely have less-capable video cards, most likely Nvidia 5xxx or 4xxx series cards. If anyone has one of these cards, let me know how the demo runs?
