> Interesting- as a bicycle rider I know that a bike helmet works by "slowly" compressing its foam over time and thus slows down the g-force on the head to a level that the brain does not slam the skull at a fatal force.  You'd think modern inertial belts would behave the same, allowing initial give and tighting over a time limit to its max.

No one was around, and I got up and started to walk to a distant house in a farming area and a car did come by.

I was in a head-to-tail at c.40 mph in a near-new car with the modern type of 'inertial' belt.  My breastbone was severely bruised, costing me plenty sleep for 2 – 3 wk.
