My mod increases distances a lot, not the superhighways btw. But they don't show in the map, aka they take long time to show up or you need to (cheat-)jump to the next sector and only then the connection appears.
If you reveal all the map and (cheat-jump-)"touch" the center of each sector, they all show-up. This is clearly regulated by some script.
I really need a direction by some script-expert modder about which scripts could regulate the show-up of the connections and expecially of superhighways, I can't find any clue
