I found out that new Microsoft Flight Simulator 2020 will generate the terrain, roads, buildings, trees, etc from OSM data being streamed from data servers. I watched a video and I couldn't believe it. Why just aircraft? Why not motor vehicles, trains, ships, boats, etc? Even a simulator in which you wake up, eat breakfast, take bath/shower, get dressed, leave your house, either drive to work or take public transportation to work, use stuff at work, eat lunch, use stuff at work, either drive home or take public transportation home, eat dinner, use stuff at home, change clothes, and go to bed.
