You misunderstand the problem - the problem isn't that the classification
on OSM doesn't match the official classification. The problem is that
until highway=road was approved, there was no classification for "it's a
road but I can't remember what type", so people have used
highway=unclassified so that the road at least gets rendered. This means
that most roads tagged as highway=unclassified are most definately not
unclassified roads "on the ground" - they are residential, tertiary,
secondary or even primary roads.
If a road is tagged as highway=unclassified, it should be a relatively
narrow road - it should not be a wide residential road with houses down
both sides, or a dual carriageway.
