Might be true, but surely it's possible that evolution should also take account of how fast a human skull can fall against something or have something else (herd of wildebeest?) run into it?!

I am an advocate of 20 MPH speed limits in towns because I believe that it gives all road users more time to react.
However, I wasn't aware that
the risk of mortality from a car collision isn't just linear – it accelerates significantly after 20mph.
The proffered explanation makes sense I suppose, with the human skull being equipped to withstand impacts at the 'maximum design speed'
