[Talk-GB] TfL Cycle Infrastructure Database (CID) conflation

Fri Jan 6 10:25:12 UTC 2023

I've also commented on a changeset that merged speedhumps into building
outlines and introduced kinks in roads. See this one, for example:
https://www.openstreetmap.org/changeset/130253893#map=15/51.4972/-0.2896
(I actually put the comment on a different nearby TfL CID changeset
accidentally, but then linked to this one in a comment)
