That's not how it works. You can't prove morality the way you can prove math. Not unless everyone involved accepts an infallible point of reference, like a book or a pope--and even then there are differences in interpretation.

All moral questions, like, "is it moral to drive an SUV?", are variants of the Trolley Problem. Whichever choice you make ends up hurting some people and helping some others. But different people have different moral axioms about how to calculate the balance of that equation.

For example, I could probably save 5 people right now by sacrificing myself and giving away my organs. The fact that I don't means that I value my own life more than those of 5 strangers.

In the same way, driving an SUV to reduce one's own risk is not surprising.

Your own morality may lead you to different choices. That's OK. My whole point is that there is no "correct" morality.

You can try to convince others to adopt your morality (which we call "proselytizing"); you can say that some beliefs are unpopular in this society (and thus demonized); you can even look down on people who don't share your morality (we all know people like that). But you can't say that they are objectively wrong. That's not how morality works.
