Obviously not very practical - much easier to block the rear sensor.

One easy way is to take a post-it, make it black with a pen, and then use a paper hole puncher to make a round dot from the sticky side of the post-it. It's just the right size to cover the sensor. Cheap, easy, and easy to remove if you don't like it.

That only works for non auto dimming mirrors. Your red knob shouldn't turn if you have auto dim.

Just tell your wife to drive around backwards in reverse. When you put the car in Reverse, the auto dim turns off.
