We understand that the kind of striped wrapping that you see on prototype cars testing in public does have some actual camouflage benefits, but some part of you will always think of a pair of pants on a fat girl at an outlet mall whenever you see it.

Or maybe it just makes different associations with its own gross people in Europe. Either way, it's a crazy looking video.
