I wrote myself into a bit of a corner here, because, after they were taken in the car, I realized I had no idea how to get them out of it. Then I remembered that a friend of mine, who was a psychiatric nurse, had the kind of button that old people wear around their neck in case they fall. If the button is pressed, the administrator calls and if they don;t get and answer, or if something is wrong, they send an ambulance. Of course, in those cases they already know where to send it, but I added a GPS chip which is not beyond the realms of possibility.
