A single anecdote is not data. I can fall by slipping on ice dressed in shorts and a tshirt, and walk away fine. But i can also do the same, but dressed in a way more padded and protective winter coat, pants, boots, then fall and twist my ankle. That doesn't say much about relative safety of shorts+tshirt and protective winter gear when it comes to falling on ice.
Back to the topic at hand, are you claiming that all of the safety improvements added to the cars over the past 20 years didn't make a massive positive impact on passenger safety during collisions? Arent't there agencies worldwide that issue safety ratings after performing variety of tests and studies (that are way more rigorous and quantitative than a one-off anecdote), and they show massive safety improvements over time for all cars in general? Or are you trying to claim that those agencies can't be trusted, and that their tests are not valid?
I am not trying to be combative about it. I am just genuinely trying to figure out what point you were trying to make with this anecdote, but all I have right now is pure guesses.
