Probably because there really isn’t any nuance in it, hand waves the physics and human factor, and it uses vague language.
Want to know what any arbitrary driver on a road has as a reference for “the design speed of the road”? The posted speed limit.
I’m not saying their argument is right or wrong, but just that this post isn’t nuanced or convincing.

There is a link there, that refers to lots of scientific research. From almost a century ago to almost today, and in a huge amount of agreement. Do you have more nuance than that?
- Dylan16807 2y agoThere's a correlation between the speed limit and the design speed, but there's also a lot of mismatch and the bias usually goes in a specific direction. A few mph over the speed limit in dry weather is rarely outside the design. And I think I have a reasonable amount of nuance. If you don't have nuance you get "the sign can't be wrong" or "always go slower". The former is objectively not true, and I've never seen anyone seriously advocate for the latter.
