Interesting concept, but no offense to you, this video isn't very entertaining.
Now what I would find entertaining, is if you did this on the front bumper, or even if you kept it on the rear bumber, face the camera outwards. Staring at the muffler the entire time isn't very dynamic.
But nice job getting your camera to stay like that, what did you do to mount it there like that? I'd be interested to learn that as well.
