When adding roads, you don't always know what classification of road it
is (e.g. primary, secondary, tertiary, unclassified, etc). Quite a lot
of people seem to add these sorts of roads as highway=unclassified, with
the idea that these can be fixed in the future when the status of the
road is discovered, but this is wrong since "unclassified" is a real
road classification.
Is there a recommended way of tagging these roads? Leaving them
untagged has a couple of problems: there is no way to later determine
that the way is a road if it is left completely untagged, and the road
doesn't get rendered.
It seems silly to take the attitude that this data shouldn't be rendered
until it is complete - the submitter probably knows lots of useful data
about the way, such as that it is a road which is accessible to cars,
the actual classification of the road isn't really as important as
knowing it is there and that you can drive down it.
Having a highway=unknown_road or similar would also help with people
tracing yahoo images - render them in a lighter colour so it is obvious
that the road hasn't been fully mapped. There are probably 2 groups of
users who want different things from OSM in this regard: Mappers want
to be able to easilly see which bits of the map are complete, so having
roads which haven't had a proper survey tagged as such is helpful. Map
users want as complete a map as possible - knowing that there hasn't
been a proper survey is useful, but seeing a road with questionable
accuracy is often more useful than no road at all.
