BMW thought it would be a good idea to bring out the new Sauber F1 car for a bit of fun at the BMW plant in Munich. Why not halt ze making of ze Bimmers for a few minutes and give the 5,000 or so workers a little entertainment? Well, we can think of a reason. BMW's driver Nick Heidfeld zooms down the strasse and does a donut for the crowd yesterday without incident. Apparently pleased with himself, he guns that big engine and heads down the street for an encore. This is where things start to fall apart. Literally.
