It’s honestly worth keeping the principle behind crumple zones in mind with everything:
If energy can go somewhere else, then less of it will be transferred to what matters.
For cars, the energy going into bending and breaking the materials of the crumple zone then doesn’t get transferred to the interior compartment.
For Xbox controllers, they’re designed so that when they drop, the batteries shoot out and go flying, which means less energy goes into the controller shell and internals.
And with a lot of laptops these days, you’re seeing the actual toughest, most survivable ones not be built out of heavy rigid metal and glass like Apple does, but out of light flexible aluminum composites. A) they weigh less so there’s less potential energy involved in a fall, and B) some of the energy gets transferred into bending the shell which will then snap back to form.
Featured comment on the first video pretty directly answers the question from @OP @Patnou@lemmy.world :
As a Firefighter I was called to an accident which turned out to be a head on collision between 60’s model Chrysler and a 2000 model Subaru. The Chrysler looked to have held up pretty good but the driver was taken to hospital with life threatening injuries. The Subaru was totalled back to the windscreen yet the mother and daughter in the car walked away without a scratch.
Another thing to point out is the newer car is “only” a 2009 model. We’ve had another 17 years since then to make them even safer still.
It’d be interesting to see how much cars have improved since then.
It’s interesting considering how the Insurance Institute for Highway Safety really highlights what is more important for them to reduce in a collision. Modern cars might sustain much more damage and be more likely to get written off as a total loss, but that will probably cost them $30-40k at the high end in most wrecks. But if a person gets seriously injured the insurance company could very quickly be on the hook for the full $100-300k in medical bills most people get coverage for.
Have I got a video for you!

I love how much this one video has done to explain new car safety.

Goddamn it’s not even close. '59 car dummy got skewered. '09 car dummy landed on a soft fluffy mattress in comparison.
