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'

Interesting hypothesis that

The explanation is that the human skull has evolved to withstand impacts up to around 20mph because that's about as fast as a human can run into something.

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?!
