This has happened several times at freeway speeds on freeways. This issue occurs when using adaptive cruise control if the vehicle encounters a panic stop situation and determines it is unable to autonomously stop in time. When the collision warning activates and the driver uses the brakes, the adaptive cruise control disengages the autonomous braking and braking is reduced until the brake pedal travels a significant amount. This increases the stopping distance and may cause an accident. The behavior of the adaptive cruise control should be changed so that a driver applying the brakes disengages adaptive cruise control acceleration (if active) but does not disengage adaptive cruise control braking (if active). I had a 2005 Jaguar with adaptive cruise control and it did not exhibit this behavior.
