This is a good thread! Lots of good takes on this issue!
I'm sort of with Bluepoof. I really like what Gary wrote.
But honestly, its probably mostly my little bike. Sure I can get it up near 100, and on most of the highways I tool along 5-10 over. I've passed a couple times on DY, but those dealt with cars doing about 12 in something like a 35 with clear sight lines. I just don't have the instant acceleration to take a pass that is at all iffy above about 65 MPH. I have to plan it, see through it and really dedicate myself to it.
I might be going all out on some highway and not be keeping up with some of your grandmas.
But hey, I ride my ride, I has my fun! I also know if I screw up I could get killed with my little bike at 70 mph just as easily as riding some supersport bike at 70 mph...physics has no favorites with brand, model or displacement.
I guess I don't have to worry about the draconian speed laws Oregon has for speeding over 100MPH...'cause I am 2slo4U Mr. LEO.
Hell, even out in the outback I tend to be a little careful, would not be too fun to be tooling at near max speeds and get taken out by a suicidal stealth antelope. In some spots you'd be lucky to have a car pass in a few hours.
