I have many fond memories of life under the Big Sky. I lived and worked in Yellowstone NP in the 70's for about 5 years when the day time speed in MT was reasonable and kind of prudent but fell to 55 mph at night. Anyway, I was motoring over the Bozeman pass (Bozeman to Livingston) on my new '79 Suzuki GS1000E at 100+mph right past a MHP that had stopped a semi. Next thing I know here comes flashing blue lights moving mighty fast so I pull over. The cop motions me to approach his vehicle and get in on the passenger side. They used to do that in MT to see how you walk, follow instructions, and/or smell funny. Anyway, he gives me a ticket for 5 dollars for wasting natural resources (fuel) and collects the 5 bucks on the spot. Problem was I only had a 20 and he couldn't make change. So, we agreed to meet the following week in the park whereas I would pay him the five which I did. Was humorous when he pulled me over as he chewed me out because I obviously had no respect for law enforcement because I blew by him without slowing down then he went through a half a tank of the tax payer's gas just getting up to speed to catch me. All and all great fun and I made a friend on the MHP.

I can answer this question more or less on two levels. Almost every transportation planner or traffic engineer (as opposed to state legislator or county commissioner) will tell you that the proper set for a speed limit is the 85th percentile speed - the speed at which no more than 15% of drivers would be comfortable going faster. Traffic engineers would also say that a speed limit at this speed will usually result in the most orderly traffic flow and least speed differential in moving traffic.
My riding experience agrees with this. Note however that when establishing "normal" speed limits for highways state-wide legislators often throw traffic engineering out the window. Some states do a pretty decent job at allowing district engineers to set speed limits.
My experience is that when the driving public finds speed limits to be arbitrarily low (55 two-lane statewide as in Iowa, Minnesota, and a bunch of other states) traffic flow gets all messed up and so does public safety. Some folks will insist that the speed limit is what they intend to drive while others are perfectly happy to take their chances at 10 or 15 over because the roadway, side friction, sight distance, and other conditions allow these speeds safely. This is an open invitation to: large speed differentials, aggresive driving, tailgating, erratic lane changes, etc.
But when speed limits are set at more reasonable speeds for the actual road characteristics speed differentials decrease and traffic generally flows smoothly. In West texas where the I-10 and I-20 limits are 80 speeds generally cluster between 75 and 80 - with occasional outliers mostly from out of state that think that 10 over is OK, but even these folks are fairly rare.
On most of the 2-lane roads with 75 or 70 as the limit most of the traffic flows near but not much if any over the limit. You can sometimes go for 50 miles without being passed or any need to pass because traffic is flowing generally close to the same speed.
Just like the traffic engineers and transportation planners say it is likely to behave.
