Then I back even more until I can see it out the side by turning my head and double check that I've got the hidden area covered by the side mirror. Then I do the other. It's much safer and easier sitting still. This also gives you confidence as to exactly where the car is that your seeing in the mirror because you have as a reference your experience during the adjusting. Much easier to trust what you see and not doubt how far or near.
