Well, doesn't mean that your car was based from a Rally vehicle you're safe at all.
Sharp turns at high speeds is a definite NO-NO for vehicles with high clearance such as the Montero and the Fortuner. Probably you're a bit safer with the Santa Fe or the Sorento. But that's a different story.
Anyways, you can rollover too on a Montero.
I think this guy was hit by a taxi at the side then it turn turtled.
Point is, don't take corners as if you're driving a my-bumper-is-kissing-on-the-ground sedan ...
