1. A method comprising:

  • operating a collision avoidance system of a host vehicle to assess a dynamic state of a first external object;

    continually establishing, based on the dynamic state of the first external object, a first value of a delay period within which initiation of an emergency maneuver is necessary to avoid or mitigate a collision between the host vehicle and the first external object;

    detecting, during the delay period, whether a collision situation exists involving the first external object relative to a second external object; and

    if the collision situation is detected, reducing the delay period to a second value less than the first value.
