I'm going to type this really slowly: When two cars collide at 30 MPH, there is less risk of injury or death than if they collide at 60 mph.Actually, diminishing returns become pretty evident when freeway traffic speeds average less than 50 mph.
At first glance, it seems like a good idea. However, the research on this subject does not support this premise.
A study performed for the Federal Highway Administration and published nearly 20 years ago came to some counterintuitive conclusions.
It turns out that when before-and-after data were examined following speed limit changes, the differences in average speeds were less than 2 mph and did not correlate with the amount that the speed limit was changed.
This is especially true when speed limit changes were within 5 mph of the 85th percentile of existing traffic speeds. The report stated that “lowering the speed limit does not mean traffic will slow down.”
Another important conclusion was “Changing posted speed limits alone, without additional enforcement, educational programs, or other engineering measures, has only a minor effect on driver behavior.”

The vast majority of fatal accidents involve vehicles going significantly faster than the legal limit.

Speeding resulted in more fatal car crashes than driving under the influence of alcohol, drugs or medication.

Changing speed limits below a certain level really doesn't do much for highway safety.
That same kind of simpleton thinking is what is used to justify mask mandates. Masks are not that effective, and the risk is not that great without one.
And Rona is not that deadly.
Do We Need Mask Mandates?
The science suggests that more states should consider rescinding them.
