https://www.openstreetmap.org/relation/6258591 used to have a note tag that said “Palo Alto residents only”, but https://www.openstreetmap.org/changeset/105578660 removed it. I believe the note tag was intended to explain the access=permissive tag, which is no longer accurate, so I removed it in https://www.openstreetmap.org/changeset/137315089 .
