Its said that cars are “weaker” because they’re now made from a softer material proper to receive impact, thus providing safety to the driver. How will safety work with cybertruck’s 30x ‘ultrahard’ stainless steel when crashing?

There is probably a difference between the stuff and design used as the energy absorbent crash structure versus the internal frame that has to hold the load of the vehicle. You can absolutely make crash absorbent structures even out of very “hard” material – it is more about the shape than the materials used. Nonetheless, it would seem intelligent to only use the very strong and expensive material for load bearing internal structures and not the “outer” part of the vehicle.
