Much, much improved this version. The new surface is very good to drive on, and I've been using the track to improve the offroad-race configurations I've been working on for personal use. I think with further refinement this'll make an excellent short-course map.
Really good layout but I agree with Jim that the mud makes 2WD cars impossible to get around here. Also the mud effect that's kicked up makes it very difficult to see from a 3rd person camera angle. I feel just like on the Rallycross track on Industrial, the insides of the corners and the outer edges should be mud whereas the racing surface should behave like dirt.
Track layout's decent, and I can forgive the scenery, but the mud surface makes driving a 2WD or low-powered vehicle (the Baja Piccolina, for example,) a chore, and the near full-throttle driving required overheats engines. A dirt or sand surface would probably be much better for multiple classes of vehicle, not just the prerunner or other high-powered, 4WD vehicles.
