Again, the drivers got injured mostly by the deceleration NOT anything else. The tires absorb NONE of the drivers own deceleration, organs moving internally, bones breaking.
THe majority of people who die in things like air crashes die from their own bodies basically tearing themselves apart due to deceleration, it's why the majority who survive any given crashes are kids, and smaller women and men, less body weight, less momentum, less damage from deceleration.
Hitting tires rather than concrete doesn't matter drastically, it certainly helps hugely but it doesn't stop a driver effectively hurting himself, the body doesn't do well decelerating from 100+mph to 0 in a matter of metres, it literally kills people. Hitting the tires prevents(usually) things like car damage and bits of the car breaking and hitting the driver which is one of two major factors that cause damage to drivers, the others being the forces exerted on the body by major deceleration. That can and often does include concussion from the brain literally smashing into your own skull.
You're discounting and ignoring it even though it's the maybe primary cause of damage to drivers, in particular in the three crashes you highlighted. Sideways impact has little to no bearing on the Button/Werdlinger/Perez crash, they were hurt by the massive deceleration. This is what is almost entirely absent in the Alonso situation, as for the 15g sustained for 54ms, I smell BS on that. The bounce off one of those tire walls, the deceleration would take a decent length of time, it's not instant, and through the entire deceleration you would be under significant g-forces.
You're also confusing what I'm saying about absorbing energy.
When a car travelling at high speed smashes into a wall and stops within say half a second, you have huge kinetic energy and it will be expelled over likely less than a second as the car smashes and stops... I'm not talking about which part of the car or driver absorbs that energy but the energy itself being transferred. When a car goes from fast to not moving ALL it's kinetic energy is transferred in that one impact. A car that crashes into a wall but continues moving for 15 seconds... again it doesn't matter which bit absorbs the impact the simple fact is that massively less energy is transferred in the impact.... otherwise the car wouldn't retain the energy to move for 15 more seconds.
There is no comparison between those three crashes and Alonso's, none, the sideways impact wasn't a major factor in any of those three crashes, the primary factor was hitting a barrier that was perpendicular to their direction of travel, the massive deceleration and that damage that can cause, tires or not, those cars stopped in an instant from high speeds. Alonso's crash wasn't the same or remotely comparable, the car hit a wall almost parallel to the direction of travel and stopped 15 seconds after the impact. Force of impact was a TINY fraction of those involved in the other three crashes.
