The criteria which StreetComplete and SCEE use for this quest make sense in many parts of the world, where pedestrians often are prohibited on sections of road like this. Unfortunately, it doesn't really work in the UK: we either get a correct (but unhelpful to routers) foot=yes, or an incorrect foot=no.

I use SCEE most days and this is the only quest of which I am aware which regularly causes tagging errors.

I'll remove the tag.
