You appear to have tagged a section of Walsall Road as foot=no in response to a StreetComplete task asking "Are pedestrians forbidden to walk on this road here?"

I'm trying to find any evidence in Bing Streetside imagery that there really is a (signed) pedestrian prohibition here. I cannot see any TSRGD diagram 625.1 "pedestrians prohibited" signs on the imagery, so do not believe that a prohibition exists. Is this a new signed restriction created by a traffic order more recent than the Bing streetside imagery?

The wiki states that access tags reflect legal access. Subjective opinions about whether it would be pleasant, a good idea, safe, etc. for a particular transport mode are not relevant to legal access.

As real pedestrian prohibitions on public roads other than those tagged as highway=motorway or motorroad=yes in the UK are quite rare and are always signed, this quest is probably better left disabled.
