If I'm in the fast lane on the motorway, it's because I'm overtaking, which I was in the process of doing.
Don't go flashing your lights at me to get me to move over when I have nowhere to go to. I'm sorry my 5mph over the speed limit wasn't fast enough for you also.
Tailgating me, chickened off when I pulled over to confront them. Words to the wise, expect confrontation if you continue this practice.
