I think we've talked about this here (was it related to the bike discussion?) but it's especially infuriating to me, because it takes advantage of our humanity. My car will MANGLE you, no matter how huge you are, but out of human decency and a respect for human life, I now go out of my way to make sure I don't hit - and therefore, hurt - you, and your response? "Fuck you, jack, I'ma going to make sure I don't trip, I don't break out in a sweat, and ALL the ladies see my swag as I mosey across this street!"
I had a friend who once said "If I ever get told I have only months to live, I'm going to put a bullet in [insert polarizing politician]." Not me. I'm going to teach some rude pedestrians a clear lesson on physics.
