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.
