[Tagging] lanes = 0

Let's try looking at this from a different direction. All roads must have
the capacity to convey one vehicle width. Some roads have formal lane
markings ( in which case the number of lanes will be obvious) and other
road types have informal (i.e. none) lane markings. On the latter, the
number of lanes is somewhat variable, and may depend upon the road surface
type, the types of vehicles approaching, and recent precipitation ( which
could fill edges, and dynamically contract the width).

So maybe trying to put a finite number of lanes on an informal road
situation may be a long process that satisfies no one. On informal roads ,
width may be the only viable metric.
