Yes the real "padding" vs that water pipe insulation stuff is a huge improvement.

And regarding the above that you did not mention, and I think often overlooked, if your seat moves any amount, your belts loosen, and your body moves, and if a minor accident is 10g's, that is a of force, and the impossible becomes more possible.

And the earlier comment about a sidebar spear, that is not a concern to worry about with a well built cage, as the forces/conditions are too remote to be concerned with in a street car, IMO.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
