Say you have a Z1 oyster travelcard, and you want to go to Brighton. The end of the zone system is at Gatwick Airport. So you tap in with your season ticket at, say, VIC, and also buy a single ticket from GTW -> BTN. If you are inspected between VIC/GTW, you can show them a valid travelcard, and if you are inspected between GTW/BTN, you can show them your single ticket.
Is this actually illegal?
