I checked an example near me (South Lane, Royal Borough of Kingston)
and the data added is incorrect, and more importantly, outdated.

https://www.openstreetmap.org/way/1073092447#map=19/51.38982/-0.26158&layers=C

In this place there used to be traffic calming with cycle bypasses,
but these were all physically removed in 2021. I updated OpenStreetMap
in https://www.openstreetmap.org/changeset/115602237 (December 2021)
but https://www.openstreetmap.org/changeset/122809678 has added them
all back in. So I assume their data is outdated (and it's also
incorrect, since these were bypass tracks, not lanes).

I'm also a bit annoyed to see changesets with 80+ streets affected
over a wide area of London with just "Add cycle lane", and it turns
out there's changeset after changeset with just the same curt comment.
Not super helpful, and I expect more from a professional.

So I'm not sure what to do next, whether to fix the map and see if
they just break it again, or to leave it alone until someone gets hold
of them and they update their procedures.

Thanks,
Andy
