There are a few advantages of having power folding mirrors on your car. One is that you can fold them in when you park in tight spots, which helps to prevent damage to the mirrors. Another is that you can fold them in when you wash your car, which keeps the soap and water from getting on the mirrors. Finally, if you have an alarm system on your car, the mirrors will usually be folded in when the alarm is set, so that no one can see inside the car.
