Well, if you are having problems with vision and changing lanes, I would surmise your mirror are angled inappropriately. There is no reason you should not be able to see a car that is either behind you or next to you with the mirrors angled properly. Most people use their side view mirrors as rear view mirrors. (it isn't like a car is going to pop out of the rear of your car...
) That is- they have them aimed at the rear corners of the car like that is an area that one can't see from the .... oh I dunno.... REAR view mirror. If you use your side view mirrors and angle them towards the side of the vehicle, you will eliminate this. I will try to give you an idea of how I have my mirrors set up.
- My rear view mirror shows me everything that is behind my car.
- As something passes out of the field of my rear view mirror, it passes into the field of the side view mirrors.
- As something passes out of the field of the side view mirrors, it passes into my personal field of peripheral vision. In my opinion, you should NOT be able to see the side of your car in your side view mirror. If you can, you are not utilizing your mirrors fully. Why look at the side of your own car as you are traveling when it benefits much more to look at what is adjacent to you?
For most people, this may seem odd, but I found that setting up my mirrors like that effectively removed the blind spot from my vehicle.
