Even worse, in Scotland there are single-track roads with passing places that are A-roads. Should they be tagged as "unclassified" on the grounds of their width?

Just to say; there are LOTS of single-carriageway A roads in the UK.

Also, I can see that, at the edges of the Primary road network, a junction might have one "primary" road, linked to several (or 2?) tertiary roads. That would seem logically reasonable to me. However, I would struggle to understand a "primary" road that is a true cul-de-sac, with no exit, whatever designation the relevant authority migh assign.

That's the thing - when I imagine an A road I imagine a road with probably two lanes in each direction, and a central reservation, but I know that many don't have those features.

Someone must be able to query OSM for primary roads that reach a node with no further motor vehicles access to see how common it is?!

I thought this was interesting: I noticed that a couple of mappers have different opinions about whether a road in OSM should be marked as "primary" or "tertiary". The road is still apparently designated the A3000, though Hounslow Council/TfL have also designated it a section of the route of Cycleway C9, and the last 300 metres are now a cul-de-sac (at least for cars travelling westbound, there's a modal filter at the end so pedestrians, cyclists et al can continue onward and there's also the one-way Clarence Road which allows cars to join Wellesley Road eastbound)
</div>
<div>
</div>
<div>
So is it still a primary road because of the designation? Can a primary road be a cul-de-sac? Aren't they usually roads designed to be a core route of the road network?
</div>
<div>
</div>
<div>
I'd argue that if anything, from a motor vehicle perspective, it's become "residential" rather than "tertiary"...
