For the novices to autocrossing.
It appears that the rollover of Buckshot77's contour during an autox is now legend on this forum.
It needs to be clarified that the car did not roll over during a cornering maneuver. The car rolled over as a result of leaving the track and having several collisions with a catch fence that had 4x4 posts supporting it, and a tire wall in front of it.
Basically, the car was sucked into the tire wall, then was snagged by one of the 4x4s at the RF corner. this caused the car to snap to its left, leave the ground, and come down on its left side wheels, then bounce back up on the tire wall as it began to roll.
The act of turning the steering wheel sharply does not make the car roll over.
