It's NJMP Lightning to be exact and it is anything but boring as I have driven it a few times.
I'm hesitant to do a big track like glen, road America, mid Ohio, etc as they would be most likely to be done by kunos themselves. My favorite part or building tracks is getting to race other people on what I created. If I spent a year on a track only to have kunos end up buidling it with laserscan data then I would never be able to race people on my track.
Building to this level takes an enormous amount of time. Last thing I want is all that time to be undermined by the almighty laser scanner.
