Thanks to Breakfast Burrito's reply to my DTM image from yesterday, I think I know the reason why BMWs park inappropriately at times.
It's not that BMW drivers are asshats per se, though some of them undoubtedly are, but that BMWs are essentially cats in their behaviour. Sometimes their owners are powerless to control where they choose to park their asses.
A cat pretty much goes to sit wherever it damn well pleases. "Oh, this is inconvenient for you? IDGAF." Same goes for a BMW.
Plus, think about it. When it has fun, it purrs so nicely!
