f=ma remains as the law of physics. If the car survives, if the driver compartment survives, it means nothing if your brains and guts are turned to chum by the deceleration forces. Modern autos are designed with crumple zones for this reason- mitigate the forces before they reach the human. And to accomplish that goal, it takes area and distance, over which these forces are dissipated.
(IE: a bigger car)

AMEN! I miss my ‘77 Cutlass, had at least half a mile of hood before the windshield taste-test. With my Chebby small block and quadrajet squirtin’ away I got 8 MPG (drove it like a rental).
