I checked out that site: some good stuff, but I like mine. It's way too tight, due to space constraints, but the angles and curves are right. I watched season 1 episode 1 where the introduced it, and sketched out the track on a map a made from Google and the TG site. Think of this as the accurate scale model - the autocross version of the track. It needs tweeking, but I think it's getting there...
