If you go back and read the original post, you might now realise
that your reply at that point was completely useless, because they
were extending a travelcard beyond its validity...

Which also gos to show that the system is wrong, because it can't easily be
understood by the reasonable man.

It's not really that difficult. People have managed for years to
understand that an extension ticket is needed to go beyond their
travelcard zones.

Mind you, having said that, TfL have recently reported that only 3% of
the people who need an OEP are using them, while many people who don't
need an OEP are nevertheless loading them.

Indeed. 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".
