I too have those mirrors. I like them to help with parking so I can see the ground marking when fitting in to a space or next to a curb.
However the bigger issue here is that most drivers do NOT have their side mirrors adjusted correctly.
If you can see the side of your car then they are NOT.
To adjust them correctly do the following:
Driver's side Mirror:
While in the driver's seat lean your head against the front drivers door window. Adjust mirror until you can just start to see the side of the car while leaning against the window. Return to a normal seating position, you should NOT see the side of the car.
Passenger side Mirror:
While in the driver's seat lean across so head is approx. in the middle between the two front seats. Adjust mirror until you can just start to see the side of the car while leaning against the window. Return to a normal seating position, you should NOT see the side of the car.
Enjoy save driving with virtually no blind spots when the sides are used in conjunction with your rear view mirror. Give it a try for a week, you will get used to it and enjoy the view.
