I've almost been in a few fights over that one....
See my previous post.

Probably the same for stoned hippies.

I hate left lane slow drivers, hate them with a passion, I call them "rolling roadblocks".
I had a guy pull right in front of me once on the highway (I was in center lane of 3), I did nothing but slow down and move to the left lane, when I was passing him in the left lane, this bastard gave me the finger. I hadn't done anything wrong, he did, and then he give me the finger. That is when I entered road rage mode.
I woulda kicked his bellybutton past his ears if I could have gotten my hands on him at that moment. I responded quite vigoursly and invited him to pull over for an bellybutton kicking, he declined. Go figure.
