I don't really yell, but an occasional, out loud, and sincere "I hope you get where you're going" goes out to all the people who do stupid things.
I see people getting frothingly angry when they have to delay a second or two to pass me, or are frustrated by me stopping at a stop sign, or when I take the lane because something is on my preferred path.
If it's that easy to set someone off, they're pretty far off balance to begin with. I really feel bad for those folks. They must have horrible lives.
