This is allegedly a video from a surveillance camera at a street intersection somewhere in China, taken on May 9, 2012 at about 3 minutes after midnight, according to its time stamp. Two cars pass through the intersection. Then a white truck comes speeding through, and at the same time a man on a three-wheel vehicle comes in from a perpendicular direction. Just as the truck is about to hit the vehicle, a "man" comes speeding into the frame, touches the vehicle, and apparently teleports it in a millisecond to safety on the side of the street. As the truck driver gets out to find out what happened and the guy on the vehicle sits on the curb, the "man" in black simply walks away quickly.
It has been suggested that the "man" is an alien or a time traveler who, for some unknown reason, needed to rescue the guy on the vehicle.
