I disagree with your example. "Acceleration between 0 and 5 mph would kill you if it were sufficiently rapid. Don't take my word for it just drop a fine wine glass onto concrete from ~20 cm" You cite a example of deceleration to prove your point of acceleration. I think a more appropriate example would be. Throw a very full water balloon too quickly and it will exploded in your hand from the gravities created by inertia. However there as been some work done, I beleive in Russia creating a dampening field. So far it requires 16 Tesla's to generate the power to lift a single frog and some modifications to the frog. It's still progress though.
