I think people that don't get in the middle of the intersection when turning left are idiots!
Are you annoyed that they have trouble figuring this out?
You cannot blame them for not knowing how to move their cars, they are idiots.
It really is annoying that people don't know how to drive, but it's pointless to lose your cool over it. If you get angry over every single thing in traffic, you will be blinded by rage and may cause an accident.
It's their fault and they suck. I will make their lives miserable.
You should not go out of your way to try and get back at them for a minor traffic issue. You can tell them why it upsets you, however being that upset about the issue is not really warranted.
