Thx, okay I didn’t get it but makes sense. Yeah it’s really stupid to “reinvent” everything and offhandedly brush away the things that have been written in blood during previous decades… I mean it’s kind of obvious that a safety mechanism needs to be fast and easy to operate. Making someone disassemble a door while on fire and blind from the thick smoke might not be the best idea. And you’d need to perform some safety dance each time before boarding a Tesla or people/passengers won’t know the strange procedures.
