Why does the American airbag inflate faster than the European one and when it will definitely not open, even if there is a collision at least 200 km/h? In which cases is it able to kill, and in which cases to save? What is the danger of the gas with which it is filled, and in general, what airbag shoots us in the face and what kind of injuries can this cause? We all know that it is good with an airbag, at least better than without it. But not everyone knows how it works and what it is actually capable of. We understand theory, practice and statistics.
