We all would like to see more content, but it really makes no sense as it still being developed.
Say you spend 3 months making the Peugeot 908 (omg!), just to find out Scavier releases a new patch with airbags, klingon language and a new UF1 badge, which effectively renders your shiny peugeot incompatible.
You'd need to develop along with LFS, and honestly, I dont believe many people would do, at least properly.
