I mentioned "performance" & "importance" as they are the definitions used for highway=trunk https://wiki.openstreetmap.org/wiki/Tag:highway%3Dtrunk "Use highway <https://wiki.openstreetmap.org/wiki/Key:highway>=trunk for high performance or high importance roads that don't meet the requirement for motorway <https://wiki.openstreetmap.org/wiki/Tag:highway%3Dmotorway>. In different countries, either performance or importance is used as the defining criterion for trunk" While =primary refers to "A major highway linking large towns, in developed countries normally with 2 lanes. In areas with worse infrastructure road quality may be far worse" https://wiki.openstreetmap.org/wiki/Tag:highway%3Dprimary > If the only way of getting from A to B is along a particular road, it's > very important. > In some of the cases that I'm thinking of, these are the only roads, so yes, very important. > Do we need to broaden our classes of construction/legality somewhat to > encompass > standards in countries outside the UK?

No, no, a thousand times no. > & yes, yes, a thousand times yes, :-) I agree that they shouldn't be =motorways, BUT, they should be either =trunk or =primary, because, in this area, they are the main road, & so are of vital importance!
