That was true in the past. But the development of the so-called Moose test Moose test has forced automakers to consider the stability of vehicles when making sudden turns, and current SUV's are actually very hard to flip on flat surfaces if their stability controls are turned on.
SUVs still have roll over death rate 2-5 times their regular car counterparts.
stability control cant change the laws of physics - a CG 36inches in the air will always be far more dangerous than a CG of 12inches.
plus the enormous weights of SUVs are just scary frightening. Trying to control a 7,000lbs object traveling 60MPH is orders of magnitude more difficult than controlling a 3,000lbs object at same speed.
Empirical Data shows the death rate for SUVs is off the charts.
