Answer:
Convex mirror are used for rear view in vehicles not concave mirror.
Convex mirror shows objects smaller and can cover a wider area than concave mirror allowing driver to look more than he would be if he were using concave mirror. SInce objects in convex mirror looks smaller so the rear view mirror makers write this line on rear view mirrors i.e.
"Objects are closer than they appear."
