I mean... If people were routinely crashing all their cars to the point they must put them in protective rubber bumpercart material, yeah, maybe stop being so reckless.
My dude, cars literally have a part of them called “bumper” that is made of rubber. Hundreds of people die everyday in car accidents and thousands more have injuries. Cars destroy buildings, crash into homes and stores, run over crowds, kill pedestrians, destroy infrastructure and even catch on fire on their own, every single day, in the thousands. This isn't even considering fender benders and near misses which are probably in the hundreds of thousands every day. If anything I think phone dropping is way less frequent than car accidents.
And I'm only using numbers from the USA alone, now consider the whole fucking planet!
Usually made of plastic, and not nearly the same thing as the ridges on a bumpercart. Besides, point being... It really is as easy as "just don't drop it". And yeah, "just drive carefully" would save a lot of lives similarly.
