    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

        If cars are traveling at 45 mph, which is a pretty standard speed for many cars to be traveling on major streets in the US, any person being hit is more likely to be killed than to survive.

        But if the speed is reduced by just 10 mph, which I would argue would be a nearly imperceptible speed reduction from the driver’s perspective, the chances of being killed plummet. Now about half of all elderly pedestrians would survive, and the chances of a 30-year-old being killed go from 1 in 2 to 1 in 4. Those are much better odds.

        most impacts don’t happen at full speed. you’re not taking into account reaction times and braking distances at different speeds.

          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.
