A parent of mine who grew up and lived most of their life on the East Coast, US, visited and we drove east across WA. At one point they could not wrap their head around the fact that we had been travelling at around 80 mph for 2 hours. And it basically looked the same out the window :)
There are a number of areas out in eastern Washington where the state patrol doesn't often bother with speed enforcement and people routinely go even faster. It is common to have packs of cars going up the left lane over Manastash Ridge at closer to 100 mph. With a closure rate of about 70 mph on the trucks in the right lane. One way to make an otherwise monotonous drive more interesting.

The US West is huge.
