Surely we wouldn't want to encourage people to add that to every single 
carriageway road in the UK with a national speed limit, when it's 
implicit once we've said (however we choose to say it) "this is a single 
carriageway" and "this road has a national speed limit sign"?

It's only a small step from "let's add maxspeed:hgv to every relevant 
road" to "let's do it to all roads it applies to regardless of survey".

Adding implicit speed limits to every object was a madness* that 
afflicted certain members of the Australian community for a while (first 
with a globally-applied "maxspeed:source", then changed to 
"source:maxspeed"), resulting in the speed limit on Rottnest Island, 
which is actually 20 urban 40 elsewhere, being set to 50 globally.

Cheers,
Andy
