What's required is a better paradigm for loading an OEP on your
Oyster-travelcard. For example, machines in Central London at places
where people start their journeys to the suburbs marked:

"Travelling beyond your Oyster travelcard zones today? Then touch here".

And, of course, vice versa for those who live in, say, zone 4, work in
zone 2, and so have a 2-4 travelcard, but occasionally travel into zone 1.

You could put them everywhere, but it needs starting somewhere - best to
choose places where the effect will be the greatest.
