The public Overpass answered 429/502 and needs ~40 s a tile while the car gives up after 8 s, so the server cancelled its queries and the car's retries added load. Now the server fetches only the tiles a car asks for, as OpenStreetMap vector tiles from OpenFreeMap (MAP_TILES_URL), decodes the transportation layer with a small reader of its own, and keeps each tile 30 days on a volume (MAP_CACHE_DIR). A fetch finishes even after the car has stopped waiting; the car hears 503 with Retry-After and gets the tile on its next try. App: OpenFreeMap/OpenMapTiles attribution on the map, retry after 15 s.
