My question is: Do they stop when you add objects? If they do, then it may be that way to prevent the AI from smashing into objects in the middle of the track. I have never tried either of these procedures, but I feel that this may be the reason.

I am just curious. I would love to participate, but i do not know how to do this. Can some1 give me a link to some software I could use?
