I know you're trying to be courteous, other driver. But when I'm sitting at the stop sign at a 2-way stop, and you, approaching from another direction with no sign, stop your own car to wave me through, you're fucking things up! Traffic behind you stops, the other lane doesn't know what to do, and we both engage in a little start-stop dance to see who will go through. It's a waste of my damned time, and I wish I had a dollar for every time this happened in Portland. It's YOUR right of way, asshole, and you need to take it, instead of giving me a dirty look when I keep my foot firmly planted on the brake.
