Make your track, than race on it. Of course, I have some sensing issues with th AI, so you don't have an AI right now to race. But if I get the sensing worked out, you will race AI's on you track you built! So, make a starting point in the editor, than build around it. Depending on what happens, if you guys like this and what-not, than I'll make smaller pieces (of course than smaller vehicles). So, post comments, suggestions, concerns and remember: Build your track first!
