To be honest I don't really see it as an option that LFS dev team
paid some real money to get track x into the game. And with iracing's approach most of the (american) tracks are already gone. There are few smaller tracks still and even fewer where you might get some discussion happening, if the actual idea of having that said track gets support.
I see at least 3 ways how LFS might get the infomation and permissions for some real track.
1) The Intel/McGill deals. LFS gets the track, LFS makes a special sim version for them.
2) Through some public project. Like there was this one guy who made a whole castle for Unreal tournament few years ago. He got blueprints and all to make it as accurate as possible. It was used to show the locations to the visitors and the actual "footage" was in game 2st person walking in Unreal tournament. The right word is preservation. To create a virtual version of something that can be used as a tool, a show piece or public attraction. Having a precise version of the track would be great for visual presentations as well. But we are really talking about "small" unknown tracks.
3. The owner of the track just likes the idea of having the track in LFS.
The bottom line is, imho, that is it worth to build a whole new track environment for some unknown track just because it is real track? Of course I'm fully biased here if I say that I'd like to see some finnish tracks in LFS, like the old Keimola track, Helsinki thunder track or Ahvenisto. Just like everyone would like to see certain track. But to find a track that gets the general ok from all people, impossible.
Lx8 with TVR Sagaris and some hilly twisty track with long front straight...
