1. A method for avoiding a tunnel vision of a motor vehicle driver driving a motor vehicle, the method comprising:

  • detecting a plurality of viewing directions of the motor vehicle driver, each viewing direction corresponding to a different moment in time, and the plurality of viewing directions corresponding to a predefined period of time;

    storing the plurality of viewing directions;

    detecting, via a control unit, an instantaneous viewing direction of the motor vehicle driver, wherein a time of the instantaneous viewing direction is preceded by the predefined period of time;

    comparing, via the control unit, the instantaneous viewing direction with more than one of the stored viewing directions of the period of time to determine a rate of change between the instantaneous viewing direction and at least one of the stored viewing directions;

    determining a risk of collision with an obstacle that is within a field of view of the motor vehicle driver;

    detecting, via the control unit, a tunnel vision if the risk of collision is above a predetermined criterion and the rate of change is below a limiting value; and

    in response to detecting the tunnel vision, stimulating the motor vehicle driver to avoid the tunnel vision.
