What really annoys me, running 66, maybe 68 in a 65 mph, divided road, you passing some people, you're in the left lane, but the right lane has lots of 60-65 mph folks. Guy gets right up on your butt for a few minutes, and you get around the right lane, and move over, all in crusie control running a consistent 68 mph. The guy goes past you, moves right, and starts running slower than you where in left lane. Just trying to hop right to the front, and actually reduce speed.... No logical reason. If you wanted to run 72 or 75, fine, keep on that that speed, in whichever lane you want, but dont run 72, up on the guys butt, then when clear run 64
