I think systematic is the thing there, like paved roads were being built, but nobody was looking at the map and deciding the most efficient place for a new road, they’d just want a road so they did one. A lot of British roads go in a straight line from random places, so you end up with odd layouts where for example, all the roads in a town are spokes from the church, because in that town the church was deciding roads.

Then of course that village becomes a city and you can’t widen these random roads that all the buildings are on, so they now have giant traffic jams if you choose to go to the centre.
