I dunno. Better to get out of the way, it seems to me. I drive fairly fast if no one is on the road. I'm leery of passing anyone where there's a huge difference in speeds, and that includes people going well below the speed limit.
My goal is to stay predictable . Go at approximately the same speed ( about 10 miles faster than the posted for perfect conditions, and reduced by five miles per obstacle - darkness, rain, traffic, curvy road etc) regardless of what happens around me, change lanes as little as possible and give a ton of warning when I do. If I I feel uncomfortable going 5-10 miles faster than posted, because of conditions, then I go in the right lane.
Predictable? Okay. Good idea. Me, too. I've been driving since the early 1960s and have never had an at fault accident.
The difference is that I stay predictably in my lane, going at the same 5-10 miles faster than posted, regardless of the speedster behind me. I don't switch back and forth between lanes dodging between moving out of the right lane for the merging cars, moving to pass the slow trucks, and moving back for the speed demons. I am more predictable than that.
I'm generally in your mode with the seeming exception that I'll get out of the way of someone who wants to go faster.
