Most cars have a centre rear view mirror on the windshield and two side mirrors on the doors.
because the mirror used is concave mirror.
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.

A convex mirror
Vehicles use a plane mirror for the central rearview mirror to provide an accurate reflection of objects behind the vehicle. A convex mirror is used as the side mirror to provide a wider field of view and reduce blind spots. This combination helps the driver have a clear view of the surroundings and enhances safety while driving.
convex mirror provide erect small and virtual image of the object.these are used in side view mirrors of vehicles so that the driver can have a better view of traffic behind.
A concave mirror is typically used to create a magnified image of an object. The mirror curves inward and can produce an enlarged virtual image when the object is placed within the focal length of the mirror.
convex mirror
When the object is between the center of curvature (C) and the focal point (F) of a concave mirror, it forms a virtual, upright, and magnified image behind the mirror. This configuration is often used in makeup mirrors, shaving mirrors, and headlights to provide a magnified reflection of the object without having to move the mirror closer to the object.
convex mirror as used by drivers in different vehicles......
To do this get a plane mirror and two pins. 1.place the first pin in front of the mirror and let it stand firmly. 2.the second pin would act like a search pin-move it until it coincide with the image of the first pin. 3.avoid error due to parallax in 2 4.read the distance of the first pin from the mirror and now the second from behind the mirror,you will find out they are approximately the same since you can't do it perfectly at home. 5.Any small object can also be used
ShapeConcave mirrors curve inward, creating a focal point in front of the mirror. Convex mirrors curve outward creating a focal point behind the mirror.Concave ImageBecause of their shape and focal point placement, images in concave mirrors appear upside down and far away. However, when you move closer, the object enlarges. If you get close enough, the object enlarges more and the image is right-side up.Convex ImageIn a convex mirror, images appear right-side up, shrunken and virtual, or placed somewhere behind the mirror.
