agreed, the passenger mirror is square, however, it is the larger mirror. the driver's side mirror is rectaglular and perhaps extends out further from the side of the car, however it terms of overall size, the passenger side mirror is most definitely larger. at least, it is in north america.
i agree that people should shoulder check each time that the change lanes, however i would think that it would be contrary to MB's commitment to safety to equip a vehicle with smaller mirrors to effectively force you to shoulder check because you can't see anything in the mirror.
