49. A helmet would not change the deceleration

The difference in 60mph-0mph in 0.01 seconds and 60-0 in 0.001 seconds is an immense difference in effect on the brain, though I may not even be able to see the difference.

In a car, the head is decelerating because the body is strapped to a seat, and possibly from hitting an airbag.

A helmet would not reduce the rate of deceleration. In fact it would make the deceleration worse because more mass has to be decelerated.

In the examples you give of when it's good to wear a helmet, bikes, motorcycles and football, impact of the head against a hard surface is causing the deceleration.

I know you're very desperate to prove that helmet laws are bad, but your logic here is utterly awful.
