But seriously, I don't even know any other real life tracks (the names maybe, but I'm absolutely ignorant of the layouts), so it's not like I have a choice.
i'd not choose bathurst, nurburgring or isle of man or a track that has such big elevation changes.
I'd choose old hockenheim, easily too awesome to race trough this narrow woods
Elevation changes equals fun. I remember NR2003 Ferrari 330 mod in Isle of Man, great feeling when you go over those little jumps. And it's not just those jumps, but elevation changes generally makes that track feel a bit more than flat tracks.
Brands Hatch or Lime Rock. All the elevation-changing awesomeness & challenging corners I love about Bathurst & Nurby but wrapped up in small, easy-to-swallow coatings.
