For a road I would tag the minimum width - so any vehicle entering
can pass along the entire length and not get stuck. <br>

It is not just about developing countries. In my part
of the US, there<br>
are many roads whicha have either no paint at all, or
have white lines<br>
at the edges (so you can see where the edges are at
night). Almost all<br>
of these roads are wide enough for two cars to pass
comfortably, but not<br>
really wider than that. This seems really obviously
one lane in each<br>
direction, and everybody who drives here gets that.
There is a legal<br>
requirement to stay on the right of the imaginary
center lane (absent a<br>
reason such as passing a pedestrian); you can be cited
for "operating<br>
left of center" entire reasonably on a two-cars-wide
road with no<br>
markings -- but that will only happen if you are left
of center<br>
egregiously or on a blind curve or rise.<br>
<br>
<br>
So that's a long way of saying that "lane markings"
should not be<br>
required for lanes=N; it is enough to observe the
local conventions</blockquote>

<div> In that example, I think it'd be better to just
tag width=* instead of lanes=*.</div>
