The mirrors used as rear-view mirrors in vehicles are

An image formed in a convex mirror is smaller than an image in a plane mirror. Because the image is smaller, more images can fit into the mirror, so a convex mirror provides for a larger field of view than a plane mirror. So, they are used whenever a mirror with a large field of view is needed. For example, the rear view mirrors in vehicles use convex mirror.
