The community as a whole decides what is good and bad data. That starts
with the local community and moves up to the OSM community as a whole in
terms of whether or not data belongs in OSM or not.

If you were able to go underground, then you'd find such data. But if you
can't- how do you know these lines exist? You probably are using a feature
that you *can* see without being underground.

Verifiable and visible are essentially synonymous in this discussion.

Yes, but we don't map things that used to be present but are no longer
present. A road used to be here but is now a building. We don't map the old
road, only what's present now.
