It’s really not. I one time had a phone fall out of my pocket while getting out of my truck, and literally hit my foot on its way down which propelled it face up into the bottom of my front tire which shattered the screen. There was absolutely nothing I could do to stop it, and there’s no reason I’d have ever thought it’d just fall out. I probably got out of that truck in the exact same way for 2 years and the phone never fell out.

The fact you’re baffled that accidents happen makes me question if you’re trolling or literally live in a bubble.
