this may be the situation in the UK, in the rest of the world (at least
non-Commonwealth), we do not have these issues, because we are classifying
the roads ourselves, rather than translating one of the different
categorizations that are locally available.

of course, under "normal" conditions, a primary road should be "better"
than a secondary road, for long-distance travel.

this is again a problem isolated to the UK, and not useful to discuss on
the international mailing list because it really only applies to British
areas.
