passengers are not stupid
they are just normal human beings in an environment not familiar nor usual to them and likely many are stressed before they even get on board
today people in all walks of life, and means of travel including the car fail to
grasp what their safety is all about and the lack of their own awareness
that trait seems to be increasing that it is someone else's fault
over-wing exits are not manned normally on most airlines hence the chat
from the crew before take off that you know you are sat at one
