In what the British media is calling a "guerrilla ad campaign," Nissan recently stickered a handful of its fleet cars with "kill" graphics signifying motorsport wins. The targets? Porsche, BMW, and Audi. Guess which one couldn't take a joke.

Turns out the cornerstone of Bimmerphile lore, that the BMW Roundel was based on a propeller against a blue sky, is just some ad speak from a long time ago. It's actually an altered Royal Bavarian Free State flag. [Wheels]
