The Apple Map street data is based on OSM. I haven't used Apple Maps so far. But is Apple using an old dataset or is OSM simply bad in some regions? I've heard that there were some problems like Apple rendering some forest roads as normal streets and so on. Because in my experience the OSM data is quite good and even better than the Google Maps data. But then again I life in a populated area with probably a large number of OSM contributors. And is Apple giving anything back to OSM? E.g. data or money?
