This is definitely the best Nordschleife simulator you can get right now! Only thing that bothers me sometimes is how 1-2 slow cars can create a gigantic que. In real life the slower cars would just go to the right so the faster cars can pass but here they just block the entire road. Also when the fast cars do get an opportunity to pass them, they just hesitate and just stay behind the slower ones. I dont know how hard it would be to code this into the AI but this would be the cherry on top of the cake !
