check out steventechno's building mods. They wont auto generate on this map, but you can build giant cities and highways with his addon

Also, With wiremod you could make a machine that would spawn a road in, then teleport that distance away, then spawn another road and repeat. I can make that as a dupe if you want since it might be fun

Dude that would be so awesome if they had that i mean i wanna have it on that map becasue it looked so cool tbh. i mean if its gonna be a highway and the map is infinite? bro. i wanna take a trip to EVERYTHING With my own maybe car i guess or maybe even the normal simfphys mod or even normal vehicles for gmod.

I don't know if the dupe would work in the infinite map though
