what you propose is not working, because speed limits are about roads, not administrative entities. You have to know the context (rural/urban inside settlement according to traffic law, etc.) in order to assign a maxspeed, and the only way we currently use to understand which context applies are the source:maxspeed values. It is very simple, doesn't require preprocessing, can be applied by everyone without looking for and downloading surrounding administrative polygons, and is also quite reliable. Why would we give this up? Cheers, Martin
