But you're also seemingly forgetting that cars these days are very safe, with airbags, seat belts, crumple zones, roll bars... this whole 'should it kill you' is not likely an issue these days. Look at all those idiots who crashed their cars going 80mph and lived to tell about it (tesla for example). The point being that if a car controlled the crash, your chances of survival are far better. So it's an option of killing someone or having a controlled crash, not 'kill or be killed'.
