Strange but interesting. This is a car advertisement from Great Britain.
When they finished filming the ad, the film editor noticed something
moving along the side of the car, like a ghostly white mist.
The ad was never put on TV because of the unexplained ghostly phenomenon.
Watch the front end of the car as it clears the trees in the middle of
the screen and you'll see the white mist crossing in front of the car then
following it along the road......
