IMHO it shows that the prefix must refer to the entity that has the power to decide the default maxspeed, and this is not always a country, but can also be a region, a state or a county, for example, and obviously, in these cases, you have to choose a different prefix. In some areas this seems to be current practise: https://taginfo.openstreetmap.org/keys/source:maxspeed#values those who add the panel in osm are not necessarily aware of the level > of government that can change its default value. > t... > the solution would again to have a default:maxspeed on a boundary. > the panels should be simplified : maxspeed:type=urban <> zone <> sign > how would that be an improvement? If you don't know who is in charge of the default limit you also can't choose a boundary where to put the limit. The main reason for this whole source:maxspeed tag is that you can't tell otherwise whether you are inside a settlement ("urban") or not ("rural"), it isn't in the data otherwise. > > > I wonder how this works, do you have signs on each and every "border" > > point telling the driver they are leaving / entering a region? > > yes, a pannel saying "welcome to the Brussels-Capital Region" > with a pannel giving maxspeed default value on main road > and on other roads? Maybe you'll need to pass a geography test to get your driving license ;-) Cheers, Martin
