> Do you mean it's not uncommon for Americans to drive all day to go camping on memorial day weekend or something

This, for sure.

Those of us who live in the midwest are often hours of boring highway driving aware from anything, so a long weekend trip does require getting where we're going as quickly as reasonably possible.

Being stuck behind some nitwit who insists on pacing the semi truck next to them at 60 MPH rather than doing the 80+ everyone else on the highway wants to go is incredibly annoying.

80+ sounds too high. 80 is good. Stopping distance is not linear with speed, damage in a crash is not linear with speed (hello deer), gas usage is not linear with speed. No one who drives over 80 has grounds to complain about gas price, especially in large suvs or pickups.

Absolutely not. The legal limit should mean it is objectively unsafe to go faster in clear conditions no matter what you're driving. It is not supposed to be the speed you expect most traffic to go. If the average speed of traffic on a road is 85 MPH and people aren't constantly screwing that up, the limit (if there is one at all) should be meaningfully higher than that.

And of course if people are regularly screwing up at whatever the natural speed of the road may be, the correct answer is ALWAYS to change the road and reduce the speed people feel comfortable driving at. Lowering the limit below the natural speed doesn't actually reduce the speed of traffic unless there's active enforcement forcing people to comply. Redesigning the road makes people actually want to go the desired speed. A fast road is a fast road, no matter what number someone puts on a sign next to it.

That's why I'm talking specifically about long, flat, straight stretches of road with effectively infinite visibility during the daytime. These are common in the American midwest, there are plenty of stretches where you can literally see the road disappear off over the horizon in a perfectly straight line. The same sorts of situations where the Germans go to unlimited, and it works just fine for them.

No argument here. My car gets better MPG at 100 MPH than a lot of SUVs get at 65 MPH so I could not possibly care less, but you also won't ever hear me whining about gas prices.
