Yup, still a thing! Especially if a lot of surrounding villages are doing things, like christmas markets. Or even within a village with lots of small stops, like a bar-hopping type deal. The buses just loop, sometimes in both directions, through all the stops. They are separate from the normal transit buses, you gotta buy their specific ticket (or it’s free) and they are usually travel bus types rather than city transit buses. The inner-village ones are just passenger vans, though.
