OH and NC highway patrols have been extra tough on speeding drivers for decades.
I can tell you that from personal experience. I live in NC, and once in the mid-’90s got a ticket in OH on two-lane US 52 for doing about 8 over the speed limit. Bright sunny day, no other traffic, I crest a hill right into an oncoming state trooper and bang! He does a U in the road and pulls me for 63 in a 55. No mercy, no warning. I mean, I *was* doing 63 in a 55 so it was legit, but still.
The worst part was that Ohio entered the citation TWICE. So when I went to renew my license in Virginia the next year, I had two speeding tickets on my record and had enough points that I had to take the written test again in order to get my license...at age 30. That’s not embarassing or anything. (I also managed to get Virginia to remove the duplicate ticket and “refund” me a couple of points at least.)
State troopers/highway patrolmen in most states, from my experience, are not to be messed with and are going to nail you to the wall if they stop you. The only times I’ve ever gotten off with warnings when being pulled over have been various local cops...and one Shenendoah National Park ranger.

VA county sheriff’s deputies will get you for five over and claim they could “tell” that you'd hit your brakes when the radar was turned on. Pretext for vehicle search, since radar detection devices are illegal there.
There are occasional, coordinated campaigns by NC state troopers when average vehicle speed starts getting out of hand, though. Locals and commuters tend to know what's going on, akin to a rolling roadblock. Truckers do too. It's the out of state drivers who try to get through it who are stopped and ticketed, invariably.
So, if you're passing through NC and all lanes are inexplicably clogged, running the speed limit, it's not inexplicable. Just ride it out, he'll ramp off and work the other side soon enough.
