I always thought I needed to see just a little of my own car on each side, but I readjusted the mirrors on my car, it works! Watch this and I’ll bet you do too!
You will never have a blind spot for an auto to hide in again.
This method as outline in the video takes a little to get used to but it works well. Lane changes and keeping track of approaching vehicles (from the rear) is simple. If adjusted properly, you should be able to see any vehicle behind or beside you in the “blind spot” through your rear view or side mirrors. Give it a try, I think you’ll be a convert.
