I've grew up in the countryside and worked on a farm as an adult and don't agree with you despite many hours in tractors, with and without trailers, on public roads.

What I hear when you say that is:

"I will follow you for several miles ignoring whaat other people would consider fine passing opportunities (and me waving my arm out the window at you trying to get you to go around) until a bunch of pissed off traffic stacks up until some guy with a Dodge Charger (or whatever, you get the stereotype) comes along and decides to pass us all at once in a sketchy way, to everyone's detriment"

And from there it goes one of two ways. Either you get the message and pass me at the next decent (to the average person, not you) opportunity or you squander that opportunity and the second guy in line passes you both of us at a reasonable time and that repeats.

Now, obviously when someone who gives off those sorts of vibes shows up I'll pull over at the first available opportunity to force them to pass but when you're talking a 2-lane with no shoulder and ditches and a combination too long to use a driveway as a pull off it could be awhile.

Listen, I get it, not everyone can pass, some people have higher standards than others for . There's people towing trailers, there's heavy trucks, student drivers, old people, shitboxes running on three cylinders, etc, etc. But that doesn't make the situation safer and for a normal person in a normal car in normal conditions to subject themselves to that is just, ugh.... misguided

The kind of people who won't pass (where reasonable, as defined by the average person) a tractor or moped or whatever in the name of safety are not creating a net increase in safety. They are creating a cluster fuck, which comes with a decrease in safety.
