[OSM-talk] definition of the main highway-tag

[Richard Mann]

Motorway is mainly physical. The point is that it most definitely isn't
defined by importance. A motorway is the part of a trunk road that has
grade-separated junctions, and is on a new alignment, or does by some other
means keep slow traffic out of harm's way.

My concern stands - beware putting a statement at the top of a wiki page
that is only partly true.
