I’ve driven all over the country, and I’ve noticed Washingtonians are notorious for that “driving one speed then speeding up when you’re passing them” behavior we all know.

My work commute takes me from Hwy 512 to chehalis and back, so I definitely see examples of the psychotic behavior your describing all the time. It often feels like there’s an inverse relationship between the number of lanes on the road and irrational driving, like the more the lanes there are, the less crazy driving you notice. As soon as it becomes two or three lanes, some drivers start making things personal on the road.
