We at Autoblog, por supuesto, love us some behind-the-scenes car development videos. We also dig smart humor, and we think the two are gloriously combined in this German take on almost every dramatic engineering/track/shakedown vid that has hit the YouTubes. Until it gets a tad too absurd, at least...

Put together by the same gents who earlier made an aluminum-foil Porshce 911 bike, this time they've worked up a car they call the Fahrradi Farfalla FXX which is loosely based on a whole lot of other cars. When they give it the shakedown in a German tunnel, well, you'll just have to see for yourself what happens. Scroll down to see what's up.
