What makes me suspect of videos talking about helmet safety, is that most videos are sponsored by the helmet companies themselves. That's like asking Specialized to make a video about the SL8 compared to a Taiwan Eisen SL8 copy. Of course the big big industry is going to say you'll die the moment you breath on it. On top of that, no bike helmet will protect you from a car going 60mph/100kmh head on.
I always tell people when on a bike don't follow the rules of the road, follow the rules of survival.
