I saw this advertisement the first time in a theater as part of a "best ads from around the world" film festival. You could have heard a mouse hiccup when it was over. The impact of the footage when seen on a fullsize movie screen was incredible.

Based on an actual event.
New cars have piles of safety technology that is designed to allow them to do well in crash tests. Real world collisions do not necessarily match controlled crash tests.
Having been through a severe side impact in a w126, where I sustained a serious concussion, the only thing I might wish for would be side airbags, but not even all modern cars had them standard until quite recently.
