Having some kind of uniformity on a large scale means you wouldn't have
to learn how to read the map again just because you moved or traveled to
an arbitrary jurisdiction.  Also provides consistency for routers, since
I can pretty much guarantee there's not a router out there that
arbitrarily changes it's behavior based on what part of OpenStreetMap
it's looking at...
