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

[Colin Smale]

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?

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.

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)
