with MrSir about leaning forward, but for me I kinda lean forward and turn back like a blind spot check but using the side window. Doing this you will see that sexy wide wheel well while you check the blind spot you had in the side mirror. Eventually you will get used to this/good at it and will not have to lean as dramatically far forward.
My number one thing is just pay attention. I find as long as I monitor everything I can navigate my way through traffic........for some reason though they never seem to get any closer when in my mirrors
