Going with the flow of traffic is fine, as far as our side of the coin, but I am just trying to iterate the fact that if you are, indeed, going faster than the posted speed limit, then you don't have the right to complain about anyone going slower than you.
If you want to run over the speed limit, fine, but mind your own business and DON'T get on my rear while doing so.
And no, I don't jump out in front of a passing truck to slow them down. If I did that, I could cause an accident, and that would make me a hypocrite. But even if I did, and you were the one speeding, not me, then I am guessing I wouldn't be the one at fault.
