convex mirrors basically provide a wider view of the image and thus makes the driver to see the cars behind clearly without any problem.

That's so but in fact they do have one important effect, that of making the reflected objects seem further way than they are. This is why many larger vehicles are fitted with twin mirrors each side: one plane for true distance, the other convex for wide angle.
Many lorries and buses also have subsidiary convex mirrors above the windscreen and doors so the driver can observe the immediate surroundings.
"Convex mirrors are used to provide a wider Field_of_viewthan a flat mirror, and are often used on vehicles, especially large trucks, to minimise Blind_spot_(automobile)."http://en.wikipedia.org/wiki/Mirror
Convex mirrors
Yes. In convex mirrors, the image is always erect and diminished, at whatever distance the object may be in front of the mirror. The convex mirror has a wide field of view and hence is used as a rear view( or driving) mirror in vehicles, to view the traffic behind.
The security mirrors.
Convex gives you the widest "field of view" (so someone does not have to be right behind you in order for you to see them).
Rear view mirrors in vehicles and are used hairpin bends on mountains (hill).
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.
Convex mirror is curved outward so that it reflects a wider viewing area. The images reflected in convex mirror appear smaller and closer.Convex mirrors are generally labeled with safety warning "Objects in mirror are closer than they appear", to warn the driver to be cautious while driving.
It is because image formed by an convex mirror is always virtual, erect and smaller than the object. They are more helpful than the plane mirror because they give a wider view.
You mean rear view mirrors? No chance of getting real image using only a convex mirror.
The Rear view mirrors are convex The Headlights are concave
Rear View MirrorThe kind of mirror used in the rear-view mirror must be convex mirrors, because it creates smaller, yet still upright images. Concave mirrors would create an inverted image and the cars you see are not upside down. Convex mirrors make everything smaller so this allows the driver to see a greater range of things behind him.
