American drivers are also entitled assholes (I say as an American driver). How DARE you tell me I can't do what I want, when I want, or change my behavior in the slightest to benefit my society/local community?
sadly, that's very often the passing lane
Heck even some of the non highway roads.
Cause I'm in MI, where we have Michigan lefts, and somewhere between surges of out-of-state transplants and COVID everyone has lost the plot on...
But overall around here, we have lots of 3/4 lane highways.
From left to right on a 4 lane...
Left lane is prettymuch always fastest traffic, with a occasional trucker stupidity around failing to not use the leftmost lane unless part of the actual route.
Next lane on a 4 lane is more faster traffic, possibly more trucker stupidity because typically they are supposed to be in the right two lanes unless there is a split incoming where they have to go left.
Next lane on a 4 lane is all of the wimpy trucks and the freight drivers following state law (i.e. we often have a higher speed limit for 'not-truck' than 'truck')
Last lane, is entering/exiting traffic; may go faster than prior lane at times but is more likely to have slowdowns from people who had at least a quarter mile to see what traffic was and attempt to match speed...
On a 3 lane, it's similar, except trucks in general will stay in the middle or right, but usually the middle.

Where it gets ugly though, is that my state is Michigan, so we have 'Michigan Lefts'.
i.e. on many roads, to do a left turn you take an intentional turn-around through a median, then take a right back at the intersection.
This normally works but sometimes it means for such roads that the left lane is not in fact the fastest lane overall.
