Which side mirror is adjusted best?

Explanation: To adjust the driver’s side-view mirror, place your head against the left side window and set the mirror so you can just barely see the side of the car in the mirror’s right side. To adjust the passenger’s side-view mirror, position your head so that it is just above the centre console. Set the mirror so you can just barely see the side of the car in the left side of the mirror. If the vehicle is not equipped with remote mirror-adjustment controls, you may need assistance when properly positioning this mirror.
