It took me a while to work out, but I think that the risky context

still lurking on your card, that journey would be unresolved (if you
touched in to start it).

This ain't exactly obvious from the briefing though, is it?

I see. So, why so little publicity to Oyster Season Ticket holders?

I was just thinking I hadn't seen any outside of this group.

I wonder if there's an element of "surely the TOCs won't persist with
this silly scheme for long, so let's not bother spending any money
promoting it"?

(c.f. the poor waiting facilities for Eurostar at Paris Gare du Nord -
because the French thought we'd soon get rid of the silly security
nonsense and they'd no longer be needed...)
