1. Idiots who pass me and then slow down. I'm on cruise control. I'm going the same speed I was before you passed me.
2 a. Tailgaters in front of me. I figure everybody has the right to drive at a speed they are comfortable and safe with. No problem, I can pass when there is appropriate space and time. But, if someone is tailgating them I do have a problem. It takes a lot more time and space for me to safely pass two vehicles. That long line of backed up traffic is not the fault of the slow driver in front. It's the fault of the jackass in the second vehicle. Please, don't be that guy.
2 b. Tailgaters behind me. WTF is wrong with these people. I drive a pick up, They are frequently so close all I can see is the roof of their tiny car. I never brake check. I figure I'm dealing with stupid people so I avoid dangerous moves. I'll slow down and move over a little hoping they get the hint and pass. If they don't, I take my foot off the gas and coast, slower and slower and slower and slower and slower until they figure it out.
3. People who drive in the passing lane because seven miles down the road they are going to make a left hand turn.
