[talk-ph] Your final say on the proposed road classification scheme

[Eugene Alvin Villar]

The OSM US community is currently redrafting their highway classification
system too. The draft wiki page is quite informative and it may be nice to
align ourselves a bit too.

https://wiki.openstreetmap.org/wiki/United_States/Highway_classification

Of course there are major differences like we don't have the equivalent of
the U.S. Interstate system and the U.S. is federally organized (there
exists state routes) and population density is not as dense as the PH.
