Yeah I also worry this advice would make it harder to back up. I drive a large minivan and use my side view mirrors all the time to check if I’m going to hit something when backing up. That would be a lot harder if I were not able to see my own car in the mirror. Although I guess all you would need to do to see your own car in the mirror would be to lean to the side a bit... so maybe not a big deal.
