SUVs are big and I think they give people a false sense of security. People dont understand handling an SUV with the higher center of gravity... think of the number of rollovers that you hear everyday.
I think its also becasue a lot of drivers out there are no-talent ass-clowns who need to be educated first on the art of driving, then on rights of riders and smacked in the head everytime they do something stupid..
I dont think its necessary that women are bad drivers.. you see a lot of men drivers in pickups, minivans, sportscars and suv's who are stupid and think they are town jocks...
