Ze Germans are all about über-precision. So why is it that they don't even have a properly functioning set of perpetual motion balls? We found these at the BMW stand at the New York Auto Show, and our first thought was the Bavarians had busted their balls. But it turns out that these are supposedly part of some ironic demonstration of some sort of BMW safety somethingoranother. It's a bit confusing, but we still think the SLR 722 GTR parking struggle over at the Mercedes stand was a bit more embarrassing.
