Great job, really nice track and pleasure to drive. I would work on the road mesh though, feels so smooth, unreal. Some surfaces work wrong, grass or gravel (pits) acts like tarmac, slows you down too much etc., some guardrails and walls need collision to be fixed. In the future I would love to see more vegetation, some 3D grass, a boulder here and there, etc., because few places look really empty. Having some narrow roads inside the triangle would be great too. Big thanks for the track, fantastic potential, solid four stars.
I'm going to see if I can optimise the track so hopefully that will create some more room.
