Back when I lived in Pennsylvania the 55 mph speed limit wasn't much of a burden. The way the roads twist and wind around all the hills, many places you can't even drive 55. And there's a town every few miles and a city generally within 50 miles. So no need to travel any real distance. But out here in Nevada and other western states with wide open spaces the 55 mph speed limit was a real burden. Many roads are straight and level; you can see for miles down the road and traffic is light. But cities are many miles apart. It is 520 miles between Reno and Salt Lake City, with only 4 small towns in between them. Case in point - this past Monday I had to travel to Reno to see an ophthalmologist. That put 402 miles on my truck's odometer that day, but that was the closest ophthalmologist to me. Can't even imagine having to drive that at 55.
So a speed limit that works for one area doesn't necessarily make sense for another area. And why an EV makes a lot of sense some places but not so much in others.
It's not so bad going from 60MPH to 80 or more, but when you've been driving for hours at 90MPH and all of a sudden hit, yet another accident/road work etc, it feels like you could just step out of your car and trot along side it.
