Kill Blind spots in cars

There is a very simple way to kill all the blind spot in your car.

And I cannot believe that we were not taught this in driving school.

It is simply so easy and so hassle-free, the only reason why we are not doing this is merely because of habit.....

figure 2 & 5 are our usual adjustments - they are WRONG.

You can actually adjust your mirrors such that all blind spots are seen in full view of your side mirrors, Just angle them as above such that the side mirrors contain no part of your own car in there. With no overlap between them and the rear-view mirror, you would be able to see any car that passes you in any of your mirror.

Why is such a simple technique which can reduce accident and save lives, not widely publicised?
