The side mirrors of a car are "concave mirrors".
So, when a vehicle is at a considerable distance(or infinity) from the concave mirrors, then it's image is formed at focus.
(Now according to rule when an object is kept at infinity, the image is formed at focus and the size of image is less than object.)
Concave mirrors converge the image formed so we are able to see the full object.
That is why, The size of the image of vehicle formed in the side mirrors is much smaller than the actual size of that vehicle.
That's why they say "Objects in the mirror are closer that they appear."
