It's not a surprise. They market The Ultimate Driving Machine*. They really do drive nice and sharp compared to other makes. So of course they attract people who think they're the best drivers, which means if anything goes wrong it's someone else's fault.

My own worst interactions have been with vehicles full of teenagers, regardless of what make of car they are in; and lifted diesel redneck bro trucks. Even that hasn't been too bad. Guess I'm lucky or careful.

* which as soon as the next model comes out becomes the Penultimate Driving Machine. That's my BMW joke, do you like it?
