text: @andygol I'd tend to agree with your interpretation that the '6th' roundabout is an artefact of the imagery. I think the whole principle of 'magic' roundabouts requires as many mini-roundabouts as exit roads. There is Mapillary sequence, but from a cyclist so not completely useful: http://www.mapillary.com/map/im/xIBy8JnGDU8IxPd7MhxSGA/photo.
  
  I think your first comment stands: it needs someone to check it out on the ground.
