  • while a camera is mounted on a moving host vehicle and connected to a processor, capturing from a camera a timed sequence of image frames at known capture times of the lead vehicle and the trailing vehicle;

    selecting from the captured image frames selected images of at least a part of the trailing vehicle and at least of part of the lead vehicle, thereby providing respective image coordinates of the trailing vehicle and the lead vehicle in the selected images;

    computing responsive to the image coordinates in the selected image frames a plurality of respective world space differential distances between the trailing vehicle and the lead vehicle; and

    determining a tailgating metric responsive to the known capture times of the selected image frames and the computed world space differential distances.
