I've had cars pass me to turn left while I'm in the left turn lane. I've had cars pass me to go straight, when I'm in the go-straight lane. I guess what I'm saying is, lots of people suck at driving. And I guess some of them are *******s, too. It's a nice source of righteous anger for me.
edit: My favorite thing is when you're at a four-way stop and a car has the right of way, and the driver waves you through after you've come to a complete stop. Way to encourage cyclists to blow stop signs~
