Well. there are really two threads going on here. One is poking light hearted fun at dolts who buy big, heavy vehicles with off road rated suspensions because they are dumb enough to think doing so improves their social status. It is a sad commentary on the human condition that so many actually believe that "you are what you drive".
The other thread is quite serious in nature and there has been excellent input here regarding safety in crashes and so forth. There is little doubt that many females feel safer on the road being in a vehicle that allows them to ride high enough to see over most of the other cars.
I have been a fan of MG automobiles most of my life, having owned a dozen or more of them. I became a stalwart believer in the advertising slogan of the MG car company - "Safety fast". The implication was that a car with nimble handling, accurate steering and good brakes would be able to actually AVOID a collision, where lesser vehicles would just lumber straight ahead to their doom, being incapable of taking any evasive action. I feel the same way today about my Miata. But realistically, in a collision with a Ford Expedition, I would be in major danger.
I was browsing a car lot one day and overheard a man telling a salesman that he wanted to buy a BMW for his snot nosed, dorky 16 year old son because he wanted the kid to be "safe". Being the contrarian that I am, I had the urge to tell the guy to make sure his son learned to drive at a real driving school, one that would teach car control and vehicle dynamics, instead of the proper use of turn signals. And while he's at it, level with the kid about the dangers of alcohol, driving around with other hormonally hyperactive teenage boys in the car and texting. The guy obviously thought sticking the kid in a BMW fulfilled all his fatherly duty when it came to putting him behind the wheel. Jerk!
When I travel to Australia or Europe, I am amazed at how different the vehicles I find there are from what I am used to back home in the good ol' US of A. A European caravan is about 1/3 the size of a typical RV in America. Pickups in OZ tend to be more the size of a Toyota Tacoma than an F 350 Super Duty.
I recognize that many people have horse trailers or boats or building materials or a gang of workers that need to be hauled. My Miata would be hard pressed to handle such loads. At the same time, MOST of the giant trucks I see are driven by one person, used for hauling nothing more than groceries, and only go "off road" when they turn into the driveway at home. I take great delight seeing drivers at the mall needing 5 or 6 tries to wrestle their behemoth into a parking space or swing wide at an intersection in the city like they were driving a tractor trailer.
The last time I visited Nantucket, a quaint and charming old whaling community off the coast of Massachusetts, I had to laugh at all the swells who clogged the narrow roads with their giant SUV's to the point that roads were impassable by anything larger than a bicycle. But they were being SEEN in their giganta-mobiles, and that was what was important to them.
Capitalism would be dealt a serious blow if we all were limited to purchasing decisions that were rational and excluded any component of ego gratification!
