You're vastly overestimating the sophistication involved in speed limit setting. Look up the concept of 85th percentile speed for more information.
As a caveat, this doesn't apply to every country, but it certainly appears to for the U.S, given that multiple DOTs list it as the "common method for setting speed limits".
