Funny old one, though a bit sarcastic. Many standards we have today
have emerged from competing standards, and that's true from data
protocols to units of measurement.

I don't think a uniform, worldwide highway class standardisation based
on road attributes is possible and satisfactory. But I think a
functional one would be, at least as a guiding principle.
