All commercial online maps decide which roads are major and which are
minor on a subjective basis. Obviously, the fact that there is a road
at point x is completely objective, but deciding how important a road
is is at least somewhat subjective. Look at any of the commercial
online map services - nearly all of them decide whether a road should
be coloured as major or minor in a somewhat arbitrary fashion, not
directly based on the road designation, the width of the road, the
number of lanes, or any other objectively measurable factor or
mathematically derived combination of objective factors.
