Hey there, I am working on this: https://wiki.openstreetmap.org/wiki/Default_speed_limits
And I am a bit puzzled by what I found out through this source: https://www.retsinformation.dk/Forms/R0710.aspx?id=2206
It reads like as long as a bus is below 3.5 tonnes in weight, it can go 130 km/h on a motorway, but above 3.5 tonnes and it is 80 km/h. Nothing in between. Is this correct, or did I miss something?
