Largest part of the problem is the passengers attitude towards this form of transportation...no one listens to a bus driver who tells them to sit and be quiet...and since the pax are paying bus fares, they take a bus riders attitude.
I sit near or at an exit, read the card, count rows to the two nearest doors, listen to the F/A speech and expect I will not need any of it.
You can lead a passenger to the airplane but you can not make him listen...my apologies to the horse.
