There are still a few places in Scotland which operate on such a system (I spent a bunch of time in one of them growing up and still go there at least once a year). There's a fish van and a meat + fresh produce van which comes on a (relatively) predictable schedule. Nearest supermarket is 2-3 hours drive, more due to road quality than physical distance, so people still go there semi-regularly and generally run big deep freezes.
