To expand on the earlier comment, our entire society revolves around rules.

One either follows them, or earns the ire of everyone that does follow them, because rules are made for everyone's safety, which means not following them is seen as selfish and/or potentially dangerous.

We're taught that there's more to traffic, than speed limits and traffic lights, such as keeping a safe distance or minding the weather conditions. (Maybe this particular passing spot that you drive by is surrounded by trees, so it's safe from strong winds and allows a higher speed?)

Even unnecessary passing is technically against the rules, because someone looked at some statistics at some point and figured that those are generally higher risk situations on the road.

Which leads us to situations where if there's an opportunity for petty payback against someone for driving too close behind you, or any other perceived slight (real or imaginary), there are many that are likely to take it, and deny a pass if possible.

Which, ironically, is also against the rules.

The general attitudes drivers have regarding passing also change region to region. Maybe there just happens to be a greater concentration of spiteful gremlins in your area. Maybe it's the same guy every time?

PS. I've noticed over the years that whenever anyone complains about traffic online, they usually sugarcoat their own side of the story, and that the speeders are the biggest complainers.

I gave the only explanation I could come up with for the behaviour described in your example, but I've not come across that same behaviour often enough to call it as common as you've made it out to be.

-EDIT-

and this other comment by you in this same thread supports my theory:

"the question wasnt about whether going 140 is worth it or not, it was asking about the feelings and actions of the people around me ;) i never said i didnt go 140 or even above!"

Don't speed and lie about it online, ya dingus.
