Driver behavior, in the U.S. follows closely the culture of "American Exceptionalism" aka, "The American Dream": the "I've got mine" (often pretentiously un-earned) vs (in their minds) you poor bastards that must be lazy or doing it wrong; the frustrated.that believe in the rat race and are perpetually learning that even a "winner" is still a rat; and other forms of exceptionalism based on force, philosophy and fark you... all expressed through their force and "face" of motorized vehicles....
What a mess....
