It's no secret that sport utility vehicles are more likely than regular cars to flip over. Studies show SUVs are nearly four times more likely to roll over than regular cars, and according to professional accident investigator Rusty Haight, rollovers can be very deadly. In a rollover, there are so many ways to die. But a computer inside the vehicle, known as an electronic or enhanced stability system, can sense warning signs of a rollover and make rapid adjustments to the brakes and engine speed to help the driver keep control of the vehicle and possibly prevent the vehicle from rolling over. For example, the computer can sense when one wheel is spinning faster than the others, when the vehicle is slipping sideways or when it is beginning to tilt.
Experts agree the technology works.
It is used widely in Europe. More affordable models do not offer the electronic stability system. This is not like picking leather seats or a high-end stereo. This is a critical safety device. It should be on all SUVs.
