And most likely - Try and schools in your area. If its correctly mapped with the school ground as an amenity=school and buildings etc. Try to reach it by car: Elly-Heuss-Knapp Realschule, Gütersloh You'll end on the wrong street without parking and a gate although the school has a parking lot. And you even end up in a oneway hell. Whenever you try to reach "large" osm objects on the routable network you are in deep trouble. camp sites, airports, golf courses, schools. People move the attributes from the polygons to nodes to make it explicit where to navigate. With polygons its up to the algorithm to guess the right point. And i had tons of stuff like this the last decade. 2 Years ago i ended up on a road at a river (by bike) the campsite on the opposite side of the river. 5km to next bridge to cross the river because the road 20m on the other river side was the nearest point on the routable network. Roads on the campsite were access=private.
