I've just added, they appear to be enforcing this based on what a staff member told me when visiting a couple of weeks ago.Not sure if Redbridge Park and Ride Oxford should be included on this list. Signage says registration is required but those who haven't done that appear not to have received penalty charges so far (it's supposed to be a free hour anyway). Multiple methods of registering including Hozah, RingGo and at machines beside the bus stop.
