You are not wrong. I drive the speed limit and if on an interstate with a slow lane and a fast lane I will be in the slow lane setting about 65 mph. I am seldom there by myself yet will pass some vehicles as well. I think for a 40 ft motor home towing a full sized 4 door truck that it is a safe speed and those who want to drive faster can pass. If I am on a two Lane mountain road I drive at what I think is a safe speed and if traffic builds up behind me I pull over when I find space to do so. I am not going to try to keep up with the many cars, some driving the speed limit and some exceeding it in that situation. You know better what is safe and have a responsibility to be safe.
