Touchdown instruction: “Two parked bicycles, and a discarded couch, all on the left. Walk just past this couch, and stop before you pass another parked bicycle. This bike will be white and red, with a white seat. Touchdown is sitting on top of the bike seat.” Other panoramas from the same location taken at other times would be highly unlikely to contain these exact items in the exact same positions. For a concrete example, see the current imagery available for this location in Street View, which contains very different transient objects. |
