I'm a crazy driver in PA, if someone is not doing the speed limit, I flash the high beams.
Sometimes these people pull over and allow me to pass. I'm always waiting to see a ticket in my mail box for reckless driving.
Man, I ran through that thing without fully understanding what was actually being asked. I have gotten a lot better; a few spot on bulseyes.
The secret: rooster your head when trying to judge some of the angles.
