@CoMaps @opencage Interesting that people made their first edits because of Ingress/Pokémon Go! I did interview a few OSM contributors for an article a few years back, and that did not came up. But it seems logical that this would be a common way.
@CoMaps OK, thank you for the link to the solved problem. I understand better now... In addition to being used for estimates (which is understandable), it was also displayed in some cases, and since that's not reality, it's not very good.
