i'm horrible when i drive, if someone is in the left lane going really slow and than i try to pass them and they suddenly speed up and than start driving really slow right next to another car on purpose, i just lose it, i pass them when i have the chance and do the same thing to them. but I try to slow down to the max. I hate doing it but i hate arrogant drivers more. The left lane is for people going faster than the speed limit!!!!!
