Fortean Photography: Ghost Riders in Japan

Recent footage from a CCTV camera in Japan appears to show a ghostly woman following a man into a taxi.  Unfortunately, the video itself is choppy at best due to the extremely slow frame rate of the camera.  If you look carefully, you can see that the supposed spirit seems to appear out from behind the gentleman himself.  It may appear that she materializes out of nowhere due to the poor quality of the footage, but in reality she was in all likelihood with the man the entire time.  It is also my opinion that the other people onscreen were aware of her presence, since they were polite enough to hold the door for her until after she was in the cab.  I imagine actual ghosts are constantly having doors closed rudely in their faces by unwitting living humans, so either the taxi driver and his fare are very polite psychic mediums, or this was a living woman whose presence is fully expected.  But that's just my two cents.  What do you think?  Is this a haunting hitchhiker, or just another Internet overreaction?

Yours in Impossibility,
