Or perhaps we could have auto top-up that allows for the intelligent user.

If you know that you are never going to make that 7 pound journey why force
the top-up system to allow for it?

How can you say never? You might suddenly discover a burning need to go to
Watford right now and the queues at the ticket machines are very long...

If you know that you only spend, say 10 pound per year why force a minimum
top-up of 20 pounds.

If I could select, "add 5 pounds whenever the balance is below 3 pound", I
would "suffer" the risks of losing my 8 pounds, but I'm not going to risk 28
pounds.

If you have auto top-up you have a registered card so there are no risks
of losing it, apart from a lengthy telephone call. Unless you can report
a lost card via the website?
