Unable to answer "What is the surface firmness of this track?" for https://osm.org/way/825363872 via StreetComplete 21.0:

this is very slippery, sloped, and risky! i almost got my renault 19 stuck in it. sorry i forgot to take a photo, but i'll link one from a similar place where my car did get stuck, about 6 months ago... so i really know what i'm taking when i say this part of the road is by far much different from the rest and way too dangerous! there is a dangerous combination of holes, dirt, rock and slope in here!! https://photos.app.goo.gl/HaAdCCWYSieZYukCA
