Passengers don't listen to the safety announcements - ever. That's why in almost every single crash where there's an emergency evacuation, you see people a) filming the evacuation with their phone, b.) passengers trying to grab everything they brought onboard with them before evacuating, c.) not listening to cabin crew telling them to remove their shoes before jumping onto the emergency slides.
All I can say is, if there's an evacuation order on any flight I'm on, and you're between me and an exit and you're trying to collect your carry on baggage to take with you, plan on being run over.
There's obviously a contingent out there who think their stuff is worth an unspeakable suffering in a burn unit.
