Adjust you side mirrors way out. Instead of looking at the side of your car go just past the dotted lines. This is going to seem weird at first. When driving on 2 lane roads you will be looking down the sidewalk on the curb side. This is okay and a better way to drive. You can still see down the sides of the car if needed or farther back, simply by leaning towards the mirror. When this is set up correctly you will see the car in the rear view mirror pass out the bottom corner or behind the headrest. Now look to the mirror on that side and you should see the car in the mirror. A car in the mirror mean you can't get over without cutting them off or hitting them. Now when you drive you can maintain a forward view without looking over your shoulder. The cars will be in you rear view then they will move into you side mirror, creating a hazard. When the car moves out of the mirror it should enter your peripheral vision and can be quickly identified when making lane change decisions.
