text: http://www.openstreetmap.org/way/17504893/history is probably incorrectly mapped as things stand.  Currently it's mapped as a bridleway, which would suggest it's not wide enough for 4-wheel traffic, yet the imagery (and previous tagging) suggests that it is.  Needs survey, and also to double-check that "designation=public_footpath" is correct.  See http://www.openstreetmap.org/changeset/31419746 .
