If a driver gets into a hazardous situation in a typical SUV, its design (box on wheels) makes it far harder to steer out of trouble

I believe this depends entirely on what kind of hazard you are talking about. A 4WD SUV is certainly more capable than a 2WD sedan in getting outof some kinds.

Impact collisions are higher per capita for the SUV fleet and all studies show that the consequences are far more serious and fatalities are higher than when non-SUV's are involved

I believe you are talking about the damage to others, because of the larger frame and greater mass of SUVs. By this logic the first target should be 18-wheelers. They really wipe out the oppposition when they collide. But the statistics on impacts -- where are yoiu getting these from?
