Malcom Gladwell wrote this useful article on SUV’s early in 2004. He asks and explores an interesting question about the perceived safety advantages of SUV’s:

I found that I was wrestling with the car. The protests of the tires were jarring. I stopped, shaken. “It wasn’t going where you wanted it to go, was it?” Champion said. “Did you feel the weight pulling you sideways? That’s what the extra weight that S.U.V.s have tends to do. It pulls you in the wrong direction.” Behind us was a string of toppled cones. Getting the TrailBlazer to travel in a straight line, after that sudden diversion, hadn’t been easy. “I think you took out a few pedestrians,” Champion said with a faint smile.
Next up was the Boxster. The top was down. The sun was warm on my forehead. The car was low to the ground; I had the sense that if I dangled my arm out the window my knuckles would scrape on the tarmac. Standing still, the Boxster didn’t feel safe: I could have been sitting in a go-cart. But when I ran it through the handling course I felt that I was in perfect control. On the straightaway, I steadied the Boxster at forty-five m.p.h., and ran it through the obstacle course. I could have balanced a teacup on my knee.
