Among statistics involving traffic accidents, you will find understeer and oversteer in the cause section. These two unfortunate dynamics of auto driving care not for what the driver wants. They are not the result of driver error. Indeed, once drivers find themselves in an understeer or oversteer situation, they become passengers on a runaway vehicle.
The term understeer describes a phenomenon that develops when the vehicle steers at less than an angle than the driver commands through the steering wheel. Oversteer is just the opposite.
