Some people who drive expensive cars are so worried about their cars being dinged by the opening of doors of cars parked next to them that they park straddling two spaces. This is a serious violation of parking etiquette that can enrage people. I myself, though not prone to get upset over trivial things, also find myself highly irritated when I see someone do that, even though I know it is small in the great scheme of things. But like most of us, I do nothing except secretly despise such people.
But Neetzan Zimmerman links to a video, of how some people dealt with a co-worker, the owner of a Jaguar sports car, who did this on a daily basis in the company parking lot.
Apparently, it cured him of the habit.
