The small car is safer to be in. The person with the small car is causing less danger. 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.
