I was an peanut to a BMW driver once, I shouted at him after he beeped at me for bumping my foot on his wheel arch as I squeezed through the tiny gap he had left because he was too far to the right of his lane, and he didn't even do anything wrong, really, it was just me being an peanut and being impatient when I should have just waited for the traffic to start moving. That was about 2 years ago and I still feel guilty. I was in a foul mood after a falling-out with my girlfriend, and took it out on an innocent bystander. Oops.
