I was not trying to insult or be condescending, I was trying to think of why it may work for me and not you. I could see how a different sitting height and mirror angle could affect where your blind spot is.I know how to use the features in my truck ! the puddle for me is in the wrong spot to see a small vehicle once its along side you,especially a motorcycle. you guys don't have to agree with me but at least have an open mind.
