Unable to answer "Does this road have a shoulder or breakdown lane?" for https://osm.org/way/30699429 via StreetComplete 45.2:

Unsure. Does this sett-surfaced inside "lane" count? It's clearly separate from the main roundabout, and not marked or used for pedestrian traffic. It is driveable at low speed, and wide enough for a normal car.
