Summary
Imagine driving in a straight line, then sharply dialling in a lot of steering for an emergency swerve to the left. Chances are most vehicles will execute this part without rolling, even a big bus or semi. However, the stage has been set for the nasty bits. All the load shifts to the right, compressing those springs, tires, and suspension parts. If the driver then swerves sharply to the right, those springs release, causing a secondary reaction that is very difficult to deal with, even in a well-balanced sports sedan. A trained driver will understand that the second turn of the wheel must be more measured, used to calm the suspension, not agitate it. Steer-settle is the mantra. In skid control, each fishtail of a vehicle increases this suspension reaction. There, the acronym is CPR, or correct, pause, recover.
