Once a friend and I were on like a 5 lane highway with pretty heavy traffic, I was in the passenger seat. So we're just cruising along, when suddenly I see this white rectangular thing pop out of the back of a truck to our right and a little ahead of us and it starting flying right towards our car and ended up landing on the hood. My heart stopped for a second while it was in the air, turned out it was just a strip of like card stock type stuff, but in the air it looked like a piece of hard plastic or something. Scared the shit out of me for about 2 seconds.
That video is ridiculous. I would have freaked out pretty hard.
