Hello bernardo60, thanks for reaching out. The Indonesia tagging guidelines (https://wiki.openstreetmap.org/wiki/Indonesian_Tagging_Guidelines#Roads) state that living street is appropriate for narrow road features that are narrow for only one car but also are "accessible to motorbikes and inaccessible to cars”.  For the living street feature https://www.openstreetmap.org/way/701109726, the motorcar=no tag prohibits vehicular travel but the classification does not seem to be an issue. I could also see it meeting the definition for track. However, the the living street feature without motorcar=no tag (https://www.openstreetmap.org/way/701109604) appears in this ground level image (https://www.mapillary.com/app/?lat=-8.5946086257659&lng=115.32843015873243&z=18.306176427320903&pKey=480661337264850&focus=photo) to wide enough to "be passed by 1 car at low speed” which meets the specific tagging guidelines. This convention is widely adopted and in practice across Indonesia as a whole. Thanks and have a good day.
