YES, I'm adding my vote to this suggestion, it is very good idea:
Serpentine road to big mountain, for Rallye purposes:
There should be created the track with many corners and serpentine roads to the big mountain. Beginning and end of the road (track) can be connected together as all other tracks in LFS (to loop / circuit). The road on the one side on the big mountain going UP and on other side of the big mountain is going DOWN and then down around the big mountain going back to the start line. Can be created this track type in LFS?
