The map should really be inverted (closed lines greyed out, operating
ones shown in colour).

I thought humans were better at spotting the presence of things rather
than their absence.

Exactly. And what the traveller needs to know is the presence of lines
that are working.

While I live away from Underground-land so am (thankfully!) an
infrequent user, I still have to think twice and remind myself that
those map are the "wrong" way round every time I need to use one.

Perhaps they help people with much less knowledge of the network than
commuters and semi-regular users? Though I'm pretty sure I've overhead
other people misunderstanding them too.
