Answer:
As it covers a large picture
Explanation:
A convex lens can produce a far larger sight, which is why it is used in car rear view mirrors.
Because they give an erect, virtual, full size diminished image of distant objects with a wider field of view.
Thus, convex mirrors enable the driver to view much larger area than would be possible with a plane mirror.
