Choosing a car to be in an accident, a bigger car is a solid choice. Of course, that skips over being in an accident at all. It also skips over any concern for others -- but so many people view that hypothetical accident as clearly the other person's fault, so may as well go with the big car.
Again, you're victim blaming here. The small car is not causing the danger. T-shirts are not more dangerous than guns just because someone firing a gun randomly into a crowd is less likely to get hurt than someone in the crowd wearing a t-shirt.
Which car is safer if you're choosing a car to be in? big or small? The bigger is safer and the smaller is more dangerous (to be in), in a multi-car accident.
My whole post was on the rationalization of the choice of size of car. Language matters, as you say. It is about people not choosing the smaller car and not being the victim due to driving a smaller car.
Yes, the escalation of size causes problems in aggregate, but not the point of what I wrote.
You are participating in the victim blaming and the arms race by conflating the externalisation of risk with safety. And there is no need to aggregate to see the effect. It is present in every individual case.
The person in the big car is not being safer, they are being more dangerous and more selfish. Just because they perceive that their selfishness is exceeding the added danger (something not borne out by the stats) does not justify it. Acknowledging the framing of the auto industry is making the problem worse.
And that’s to say nothing of what happens when the person being hit is a pedestrian or cyclist.
