Serious question, where’s the road? Is there one? Like, if I want to get to my house, do I need to climb my neighbor’s stairs?
There is a main road in the “middle” and then small side paths that go to these houses. And the houses usually share common walls. It is all VERY tight. I wouldn’t even bike on most of those roads because it is also very hilly and steps all over. Literally thousands of years before cars so most people have to walk.
