[Talk-GB] highway=primary cul-de-sac?

[Steven Hirschorn]

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?!
