My problem with KartaView is that there is no new images in my city since ~2019, and very little is covered. So no one here uses it. While someone needs to start, I guess, it wont be me. The municipality where I live has however mapped >800 km of city streets themselves in Mapillary, so it's a good source to expand on and where I can fill in the gaps with cycling related stuff.
