You cannot always correctly assess your own ability to drive. Imagine the following situation: During a long journey on a straight, monotonous stretch of road, you slowly become tired. You hold the steering wheel rigidly and only steer abruptly. The standard fatigue detection system registers this typical driving behavior, compares it with the length of the journey and reacts immediately. An acoustic signal sounds and a message in the multifunction display advises you to take a break. The fatigue detection system literally encourages you to continue driving after a rest, rested, so that you can get home safely.
