I remember story from my youth about super-sturdy Russian car called "
Volga". Its chassis was so stiff that you could hit a tree without denting it. The downside was that all the energy of the crash would transfer to you body and you would die.
Car manufacturers are smarter these days; in addition to all other safety features, cars have so-called crumple zones, which absorb the energy of the crash. I saw more than one car with completely crushed front part and untouched cabin. This lesson has yet to be learned by phone users and manufacturers.
