How can I get an elderly parent to stop driving?

In 2003, Virgin Trains introduced some new set-down only or pick-up only stops into its passenger timetable. What is unusual about these restricted stops is that they are in the middle of the train journey, rather than the common practice of instituting set-down only stops at the next-to-last station or pick-up only on the second station of a train’s run. For instance, some South-North trains are pick-up only at Oxford, despite Oxford being the sixth or seventh stop and previous stops not being pick-up only. The company has stated that these are enforceable by means of fines; for example, a passenger leaving the train at a pick-up only stop is deemed not to have a valid ticket, and could be charged accordingly, although exactly how this can be enforced once a passenger has left the train is unclear. The apparent intention of the restricted stops is to stop short-distance passengers from overcrowding the long-distance trains, although they might also put some bona fide long-distance travellers off using the trains.
