If they don't, could someone please help with tagging them correctly? Or should they just be removed?

I don't know if you take this approach to all editors with less experience than you. Fortunately I know that rudeness and a blank refusal even to consider discussing the issues raised by a fellow good faith editor are not typical of this project.

Because the mapping treats the low kerb, not a barrier with the Northern road, identically with the high hedge, a definite barrier with the Southern road.

Looking at it now on another desktop (Standard OSM Mapping and iD editing) my edit seems to be there. It wasn't showing on a laptop a couple of hours ago, and I assume you'd reverted it. It's also not showing on GuruMaps on iOS, but maybe there's a delay in updating that. Maybe I'm misunderstanding some caching issue?

Anyway, would it be worth adding the hedge to show thast there's a barrier between the path and the roadway of the Southernmost cul de sac?

On both occasions I walked the path, a few years apart, the map misled me into heading West down the Southermost cul de sac. The way you have it now is at the very least highly misleading, but if you think there’s no way to improve it I’ll leave it to your far greater mapping experience.

Hi Dave, I believe my edit was correct. The Street View you linked to shows the Northernmost of the two parallel cul-de-sacs called Claremont Walk facing West, with houses on the right, and also on the right a driveway with garages towards the end.

The path is on the left, behind a metal fence and immediately next to a tall hedge. It departs from the left hand pavement approximately opposite the third of the terraced houses on the other side of the road, and doesn't go all the way up to Claremont Buildings/George's Road. The line of the path can (just) be seen in Google satellite view.

The Southernmost cul-de-sac doesn't have Street View, but that runs along the far (Southern) side of the hedge from the line of the path.

Perhaps this is trivial, but a walker looking for the path can't expect to find an entrance to it in Claremont Buildings/George's Road. You have to walk down the Northern cul-de-sac to see it.
