All "footpaths" originally created by JDM12 are suspect! None have been tagged properly (surface, access, etc - those that actually exist are mostly concrete sidewalks & should be tagged as foot access, bikes dismount) and many are not actually paths at all but concrete curbs.
Also be on lookout for footpaths drawn (usually sloppily) over top of existing pathways or crossing, pathways that do not connect to existing crossings and pathways that do not connect to roads which the cross. In general, it is a mess.

Some editing done - some non-existent segments deleted, however tags are still required and many remaining segments and complete pathways don't connect to anything so they can't be used properly by router.
