I'd love to see new tracks as long as they are focused on a more technical layout, narrower than other tracks already in S2 (maybe like the FE width, but that's still too wide in places.
I'm thinking a track a bit like Knockhill - built on the side of a mountain, narrow, hilly, technical and short with tonnes of character.
I think LFS has too many long tracks that are suited to single seaters and GTRs and not enough tracks that are suited to UF1/XFG, even the XFR and UFR and Turbo Class cars.
I know I'm going to get a beating for this, but I'm a fan of short tracks, of which on LFS there's only 4 or 5 (not inlcuding reverse variants - FE1, AS1, SO Sprint 1&2, SO1). Most tracks are 'Grand Prix' length which take ages to do in above mentioned cars.
