The way I've heard it from drivers, suvs gives you elevation to observe the traffic and the mass to make your bad behavior problem of the other side while you gain real numbers safety.
That's a pure negative sum game though. The elevation gives you only a relative improvement in visibility if other vehicles don't increase in elevation in response, at the cost of sightlines for other road users and especially pedestrians, unless they wear platform shoes.
The same of course goes with mass.
Usually this kind of negative-sum-prisoner's-dilemma incentive matrix is resolved by government intervention which changes the payoff structure.
