Even without chariots, road are useful: pack animals and people on foot will move much more easily if there is a solid path that doesn't turn to mud when it's raining, that's clear of obstacles and relatively smooth.
- wickawic 9y agoIt was a contrived example but charitably there are lots of inventions that are only useful in light of other inventions.
