The speed limit might possible be 25 mph because a human could survive being hit at that speed.
Going this fast in a 25 mph zone is quite likely endangering someone else’s life, not just a private game of Darwinism.
Humans can't survive being hit by a car at 25 mph.
The primary purpose of most speed limits is tax revenue, which is why most speed limits are not based on safety evidence. The local authorities just tweak the limits to maximize profits.
fun fact, the US isnt the entire world
outside of the US, the roads and areas are specifically designed for certain speed limits that are proven to be safe
most impacts don't happen at full speed. you're not taking into account reaction times and braking distances at different speeds.
Facts disagree with you. Humans have about an 80% chance of surviving a 25 mph impact.

The article you linked doesn't say what you claim it says. It discusses a 25moh car hitting a pedestrian, which is wildly different from a true 25mph impact in general, because most pedestrians will try to dodge.
And do you have some data for the “most pedestrians will try to dodge” claim?
