You could have some robot force you to face toward the FA and listen, yet some wouldn't pay attention in the moment or even retain the info. I stop what I'm doing, I pay attention, and I even review the safety card to ensure I know what to do. That's as a frequent flyer and a private pilot. Only takes a minute of my time. But I'm a little different, as I always think of best exit strategy, also with a plan B. This includes my home, every hotel, heck, every building I enter. It's not just airplanes, but any event, whether fire or terrorism, has made me aware of my surroundings at all times. I've had my share of events in life, and I prefer to keep on living.
