I have to agree, nothing ticks me off more than being stuck behind someone going slow in the left lane. I don't speed like I used too but I do go about 3-4 mph over the speed limit just to keep me from sitting in a group of cars. Another thing is the PPl who refuse to adjust their cruise control and will sit in the left lane riding side by side with the car in the right lane refusing to touch the gas pedal and move around them.
Oh, and the trucker who jumps into the left lane at the bottom of a hill and rides all the way up next to another trucker. Hmmmm, maybe I should just quit driving.
99% of the time the driver being passed sped up to match the passer. I had a clown do that with me; I overtook him at cruise controlled 68 (in a 65 zone) and pulled out to pass; as I pulled ahead he pulled up to half a car length ahead of me. I gave it some gas and he matched it. Then I dropped back to 65 to pull in behind him; damned if he didn't slow down to block me! Just about that time some a-hole in a Beamer screamed up my rear flashing his lights and zipped by with about two feet to spare.
For a moment I could understand the desire to brandish a weapon; thank God for self control!
