Spktyr’s not a nutcase, he’s correct.
As an example, on the south side of Chicago (South end of the loop if I remember correctly) the posted speed limit is 45 mph. Average traffic flow speed is 65 MPH. If you are going 45 you are a traffic hazard and need to be removed.
Another good example is I-65 between Indy and Chicago. Posted speed limit was 65 (Might be 70 now) and traffic flows about 10 mph faster. Including the police and State troopers. Keep up with traffic and you have no problem. Go the speed limit and you impede traffic behind you for miles.
Slow drivers on the interstate cause more accidents than fast drivers.
You have to keep up with the flow of traffic.
Yup.
Here’s a personal case in point, taken from my helmet camera a few years ago. This was on the President George Bush Tollway in North Texas. It was posted for 70mph. I was doing 80mph. Everyone and their brother was passing me.

I’ve seen school buses, cop cars not responding to a call, fire engines not responding to a call, code enforcement vehicles, city garbage trucks, you name it, all going 20+ over, constantly.
The only place I’ve ever been in the US where the flow of traffic wasn’t 10+ over on the highway?

Out in West Texas where the legal limit is 80mph, and down around Austin on SH130 where it’s 85mph. Very few people doing 90+ there.
