"purposeful" in this case translates to "mapping for the router" *1 in
OSM-speak. There is a convention in OSM that two highways represent
two carriageways, so when a single carriageway with a legal divider is
mapped like this, it is simply "wrong" according to our conventions.
This has nothing to do with the context (large city vs. countryside).
