Re: Multi level towns
"So it'll route me to, then along a busy main road, when I was already on a quiet parallel road that goes to the destination"
In some cities, that would be a prudent survival strategy.
I was visiting a friend in one US city, who told me we were safe on the main street where we were, but if I walked a block away from it, I would probably not make it back.
I also remember a similar warning a decade earlier while on a university exchange at a city 2000 km north of the first mentioned city. I do recall that the university residence I was staying in had 4 armed guards in the entrance lobby... and I don't mean batons, tear gas, and tasers.
