Adjusting side view mirrors

Talk about setting people up for problems! First I've never set my mirrors that way. How can you tell the relationship of the car in the mirror against your car? You just can't verify where the car is exactly located. I set my mirrors so I can see the very edge of the side of the car. This gives me the perspective of my car and the car in the next lane! I always look in the mirror and give a quick glance to make sure no one is next to me. Either way you set the mirror you should always give a quick glance to make sure no one is next to you!

I've gotten into customers cars at work that have their mirrors set like the article suggests. I'm always wondering where the side of the car is! Can't be too safe to set them like that!
