Because completeness is hard to define (do you include footpaths etc.)
and we have no way to record it, I don't think we can talk % complete in
any useful way.

Therefore I think we're stuck with option (ii).

If we can get OSM on TomToms or a similar devices that people can take
with them all the time, they will be able to spot the bits of the map
that are missing and add them as they are driving around normally. Once
that happens, I'm sure we will very quickly complete all the roads that
people actually use, if not all the roads that exist.
