The BMW is a German car brand popular with drug dealers and hooligans across Europe. Anyone with "something" small and the need to compensate tends to gravitate towards the BMW - the ultimate penis compensator.
As such the tendency to drive like a maniac and king of the road is extremely prevalent amongst BMW owners. Expect them to overtake at 40% the speed limit, cut you up on off ramps and to park on the side walk by a hospital or school as they feel fit.
Many psychiatrists believe that owning a BMW is a reflex action to draw attention to the owner. Having no "physical attributes" to speak of, BMW owners must compensate somehow and 1/2 ton of metal seems to do the trick.
