Don't Do This!!!!!!

I'm usually pretty mellow when I drive, but there is one douche move that people keep pulling on me that makes me want to kill someone. It's so rude and so dangerous. Here's how it goes. I'm driving straight on a major road, so I'm going pretty quick. I see a guy at the approaching intersection waiting to make a right turn into my lane. There is clearly not enough time for this person to safely merge in front of me, but they pull out anyway, causing me to slam on my brakes. Really? How can a person be that stupid or rude? This has happened to me several times too. What the Fuck? Anyway, here's a little drawing to illustrate.

 Please excuse my lazy ass drawing, but you get the point.

If you have done this by accident, wake up! If you have

 done this because you're a rude, impatient dick, I hope

you crash your car soon. Don't get hurt, just wreck your car real good!
