Horse-boy shows up on Google Street View again

This is a screen cap of Google Street View somewhere in the UK. It shows a mysterious man with a horses-head, or alternatively, a horse with a man's body, standing near the street. This is the second unexplained appearance of Horse-boy on Google Street View. Click on over here and see the original sighting. Then explain if you can, what it means in the comments section.

I, for one, welcome our new horses-head overlords.
