I like it; sometimes I wish it had weather change to please the photo mode fans. I also wish it had some sort of interior course as an optional variant; maybe even a new location for track editor. You could edit a track on the interior, and then have connecting roads back to the exterior oval as an option. Because the area is fictional, you could have an infinitely variable amount of corners and banking degrees, (It would be cool if it was all man-made and modern-looking to mach the outer oval) maybe even elevation changes.
Now I'm kinda changing the direction of the thread; "I love the track, But I wish there was more to do with it" is how I'd summarize how I feel about it.
Also, I like how the AI seems to be really aggressive with overtakes - many times AI cars have spun me out from minor bumps at high speed.
