I think what these were suposed to be for was (in the case of e.g. relation/2026188/history ) "when cycling down the A19, use the cycleway down the side along way/150367993 , not the sliproad itself".
I think the contributor who added these came and went 9 years ago and no-one ever asked them about them: http://resultmaps.neis-one.org/osm-discussion-comments?uid=330434 .

(and a stream near Castleton)

... and another scooter rental place off Piccadilly.

In what way is a tag that is unnecessary an error, and in what way does the change improve things? The original changeset comment talks about "*ERRORS*" and says "*IMPROVE the quality".

Hello again DaveF,
As I said above, you've changed natural=sand to surface=sand on way/996018658/history here. In leisure=golf_course it actually says "Recommended to also tag with surface=sand or natural=sand", so I don't understand on what basis you are making the "sand" changes here?

To both of you - just changing the name back and forth will achieve nothing in the long term.

Perhaps someone can post references to local signage?

Hello Pankok and welcome to OpenStreetMap!
It looks like you've accidentally changed a hotel way/956569746/history into a park. Have you any idea how that might have happened?
Best Regards,
Andy

In osm.org/browse/changeset/111372699 I said "As can be seen from http://osm.mapki.com/history/node.php?id=248436981 this city has had the name tag changed several times in the last few months. It'd be really helpful to understand the reasons behind this change."
You've been discussing this with another mapper on changeset/113104060 , but it doesn't seem as if that has come to any conclusion yet.
