From my experience the more touristy cities might have a handful (e.g. Amsterdam yes, most other Dutch cities no), so for me it's way more rare than "a metric ton" in "most European cities", but maybe I haven't been in the right places, I wouldn't know if it's more common around the mediterranean for example. Also, on the street it's much louder and more bustling around than in a subway (or on a train or even in a bus for that matter).
