I don't really care which lane you want to drive in or how fast/slow you want to drive, so long as you're not a rolling road block. Pick a speed, set the cruise, but, pay attention to what's going on around you.
My hottest hot button, coming up behind me, I move over, you get close, slow down, and sit in my blind spot.
My 2nd hottest hot button, I've got the cruise set, I get to your blind spot, and you speed up as you realize someone is about to pass you, and you don't speed up and pull away, you speed up just enough to keep me in YOUR blind spot.
3rd hottest hot button is newer and a result of adaptive cruise. People are running their adaptive cruise, not paying attention to their speed or any other cars around them. As you pull up to pass, they look down, realize they're not anywhere near where they set the cruise because adaptive has slowed them down behind a slower vehicle/semi. They've been hunky-dory behind that semi for 5Mi as I've been coming up behind, but, when someone is about to pass, they gotta jump out in the left lane and start pacing the car next to them because they don't re-engage the cruise at a higher speed.
I don't like that either, happened to me yesterday on the Interstate @ about 80. Nobody behind us. There's a semi up ahead ~2mi up. I've had the cruise set in the right lane for ~10Mi and the guy's been drifting up and dropping back behind me, obviously not using cruise. Finally decides to pass, gets 2-3 car lengths ahead and darts back over to the right lane. He had miles of open road in both lanes, no one ahead for quite a while and nobody coming up from behind.
