Indeed. I'm wondering how things like "Administrative classification
in the UK, generally linking larger towns" (primary, from the
highway=* page) could possibly be taken as describing the physical
structure of the road.
Personally, I think that the road hierarchy from trunk down to
tertiary doesn't really have a strong definition, and that region-
specific mappings (the International Equivalence table) is what people
generally go off[0]. The distinction between motorway and trunk seems
to be somewhat consistent globally, and the sub-tertiary values
(unclassified, residential, et al) have globally useful definitions,
even if people don't always agree on what they are.
[0] Although I just had to fix the Australia section to match the
Australian Tagging Guidelines and what people do. The ABC
classification mappings were off by one level
