I'd wanted to do one of these

To the owner of the red minivan,

It is bad enough that the cars in front of me have already cleared out, despite the fact that the sign clearly says "Speed Limit 45 mph" and I am already pushing 50. Then you have to have your car lurk so close to mine, as if you are rushing to be at the side of your wife and your firstborn, only you can't, because I am trying to keep the car from veering out of control. I understand that I may be keeping you from a kodak moment, but I just can't stand it when you look at me like that. I am a very fragile person. With a very fragile driving confidence.

Sincerely,

Two-month old teen driver
