These are all wonderful suggestions on proper mirror setup. And I will try them out to see if they are better than what I have been using for the last 40 years.
However, the point of this thread was that the driver side mirror on my car does not have sufficient side to side travel. And since this was the second X1 that I noticed this on, I wanted to see how widespread this was. Whether or not I should be looking at the door, I still should be able to move the mirror enough to see the door.
Thanks in advance.
