I disabled my side cameras
I also found the side camera switching a dangerous distraction. It was useless, as it took about three seconds of video mess during the switch, and by that time I was almost done changing lanes. So not only was it distracting, it was also useless. My camera switch box looks different from those shown in others' replies, but I also just cut the two turn signal wires so that it would stay on rear view. I'm now looking into additional monitors for viewing multiple cameras without the switching while maneuvering.
