I’ve changed the access permissions on the track to remove permissive access for motor vehicles in https://www.openstreetmap.org/changeset/165972109, as I guess you intended to mark it as a permissive alternative to the bridleway, not something that anybody is allowed to drive their car down.

Please let me know if that’s not correct (and please try to leave more descriptive changeset comments in future so this kind of guesswork isn’t needed! See https://wiki.openstreetmap.org/wiki/Good_changeset_comments)

Thanks!
