Why are rear-view and side view mirrors on vehicles convex?

This gives the driver a wider field of vision. Usually only the passenger side mirror is convex. The reflective surface of a convex mirror curves outward like the outer surface of a ball or globe. An object observed by looking at its reflection in a convex mirror appears to be smaller than actual size.
