Extract: auto industry market researchers who determined that typical SUV drivers
"tend to be people who are insecure and vain. They are frequently nervous about their marriages and uncomfortable about parenthood. They often lack confidence in their driving skills. Above all, they are apt to be self-centered and self-absorbed, with little interest in their neighbors or communities."
The sad implication of this statement is that according to the automakers (not Bradsher-this is the auto makers talking), if you buy an SUV then there's a good chance that you possess an obnoxious personality and are fundamentally timid and insecure beneath the surface."
Perhaps that explains the experience many have with these types. Very sensitive to blows to their self-esteem - but unable to cope.
