Here's what the setup to this little piece of video says:
Supposedly this is a car commercial that never aired. I'm thinking that it is more probably a very good student project using Computer Graphics. About 2 seconds into the "commercial" notice something moving along the side of the car, like a ghostly white mist that looks humanish.
All I'm going to add is that this really, really got me.
Update: Here's another link to the movie, in case the one above is down.
