I disagree with your numbers, because it is not stated, any assumptions and extrapolations made cannot be taken as fact.
SUV death rates fall
From this article, "But drivers of today's SUVs are among the least likely to die in a crash, the Institute's latest calculations of driver death rates show. The change is due largely to the widespread availability of electronic stability control (ESC), which helps prevent rollovers. With the propensity to roll over reduced, SUVs are on balance safer than cars because their bigger size and weight provide greater protection in a crash."
My wife and I are very good drivers. We allow plenty of following distance, obey the speed limit, and brake early. My primary concern is for the safety of my family. I want a vehicle that will protect us from all the other idiots out there. Simple physics, and the IIHS, show that larger vehicles are safer.
