The width default unit is metres, see
https://wiki.openstreetmap.org/wiki/Map_Features/Units for other units
and how to state them.
For a road I would tag the minimum width - so any vehicle entering can
pass along the entire length and not get stuck.

I can see value there, but the width has to be an average, and the
cleared area for passage of vehicles.

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