Years ago, when riding my bike across Montana, I was riding over the posted limit, but being passed by many vehicles. When stopped at a rest stop, I asked a guy about speed limit enforcement. He replied "if stopped, the fine is only $5.00, and ticket doesn't show on your record". I rarely got passed after that, and did lots of passing myself.
I also remember riding in Canada, yes speeding, and many cars would pull to the shoulder to allow me by. Amazing, cars actually pulling over for a motorcycle! In my experience, Canadian folks were more courteous, which was noticed, beginning at the border crossings.
