waaaaaait a sec. You just might be part of the problem. Keep right except to pass? I love that I more than occasionally have to go into the far right lane to pass somebody because the left two lanes are people going 65 and 67. If you're cruising, you're probably on the pike, and there aren't that many exits. Slowing down from 65 to 60 every 15 miles is not that horrible. When I had my POS blazer, which had a top speed of 72, I'd set the cruise at 65 and chill in the right lane. I had the exact same experience as you, where nobody bothered me, but I was in the right lane.So what I like to do on is get into the middle lane and set the cruise to exactly the speed limit. I don't like the right lane because I'm constantly having to slow down or move over for people merging on and off the highway (if there are only two lanes I use the right).
I like to set my cruise at 72 and just go for it, usually in the middle lane and then the left lane to pass, but in eastern MA people only do 85 or 60, so I generally end up going faster than I want simply so I don't have to weave through traffic doing 70. Once I get past 84, it's like the gates of heaven open up and I can suddenly do my 72, then move over to pass, then get back in the right lane. It's magical.
