Well according the NHTSA
LTV's make up 37%of vehicle registgrations
Cause we all like to read boring gov't reports
They also make up 37% of total accidents, therefore a 1 to 1 relationship
Another report
But they are involved in a disproportionate amount of accidents involving death. So maybe there might be something to the 'remote' argument but since a large part of it is accidents is with cars it would seem that the passsengers of the cars would be just as 'remote' in these cases averaging it out some.
But its not just small percentages more, its multiples more dangerous, 3X in say an F150 over a Windstar.
I've driven lots of trucks, 1 tons, 3/4's, extended halfs, even a few grain trucks, 3 tons  and I always find the learn curve greater when I jump behind the wheel of new truck over a new car just getting accustomed to the significantly different handling charcteristics.
I think that may be the biggest deal,  you get on loose gravel in a truck you can get in trouble in a hurry and yeah if its remote your survival is going to go down but it takes a more experienced driver to handle big and I think that is what is making the disproportionate statistics.
The econo boxes aren't safe enough for me either, although a Civic fairs pretty good, not enough safety built in and outmatched by the LTV's on the road.
I might as well answer the OP's original question since since I haven't done that yet.  No SUV's aren't going to go anywhere, they will make them safer and more fuel efficient.  There will always be a market niche for them they are just TOO handy.  I just sold mine a month ago 

 but when the wife goes back to work and the car has outlived its usefullness, I'll be getting another, been relying on the FIL's too much
