Higher raates of speed clear the roadways quicker, or if you like allow the roads to carry a greater traffic load.
Problem is disparity in speeds.
Most people drive according to the speed of the traffic despite or in spite of what is posted.
Speeds are still lower, than pre Gerald Ford or Nixon's 55mph.
In Tn the limit was 75 and was going to 85 before that.
All the semis on the road is a problem for everyone else, and the reason they are there is Free Trade.
They are hauling everything from ports and distribution centers.
The only logical solution, which doesn't seem to be in their intellect, is same speed for both trucks and cars, and mandate trucks stick to right lanes.
Everyone who runs I69 In Indiana knows the problem of Truckers playing games, micro passing etc at their limit, of what is it now, 65, while everyone else on the road is doing a slow burn trying to get around them. They will run side by side talking on cbs or phones for miles on end.
The various companies do set their rigs to 65,67,68, and a few 70. And they all create problems like a rolling roadblock.
