Question

convex Mirrors are preferred in automobiles because?

Answer 1

Because the image is smaller, more image can fit onto the mirror, so a convex mirror provides for a larger field of view than a plane mirror. This is why they are useful. They are used whenever a mirror with a large field of view is needed. For example, the passenger-side rear view mirror on a car is convex

Answer 2

Thanks for your question !

Convex mirrors bring us more large picture of the object rather than it is. So rather than plane mirror, that picture is larger.

Also it is is said on it 'Vehicles may appear closer than they are'.

Hence, to get large and virtual view of the object, Convex Mirrors are preferred in automobiles.
