It is written on the rear-view mirror that the vehicles coming from behind are actually nearer than what they appear to be. How is this explained? Object and image relationship for the convex mirror does not give any explanation to this statement.Can any physicist help?

This would mean, as you point out, that the mirror is slightly convex, giving you a better field of view when you look in the mirror.
Generally your interpretation of the mirror image (or any image) is that it becomes bigger as it gets closer. The mirror image appears smaller than it would be if you are looking at it in a straight mirror. It appears to be farther away than it actually is. If you know this, you will adjust accordingly....

In rear -view mirror it is often written, “Objects in the mirror are closer than they appear"
The statement always confuses many.
In Physics we don’t say ' Objects in the mirror'. Instead we use “Image”.
The statement is to be read as, “Images in the mirror are closer than the objects (producing the image)"
In convex mirror objects that are far away from the mirror will produce a virtual image nearer to the mirror (at the back of the mirror).
Therefore the words, “objects in the mirror” should be read as ‘Images’
Further when images are seen nearer than the object the warning becomes superfluous ( not required) and it will be better if the statement were not there.

In the rear-view mirror the vehicles are nearer than they appear,( as per the writing on the mirror) due to convex mirror and their distance is from the surface of the mirror, so you have you to minus the length of your vehicle from the vehicle comming from back.

A convex mirror reflects more of the scene behind you than a flat mirror does, and therefore any object within that scene will occupy less of the image than it would if seen in a flat mirror. Hence it appears to be further away than it actually is.

no longer something. I had an air freshner that appeared like 2 cherries via fact my daughter fairly needed me to cling it up, yet i could no longer stand it. It bothers me to establish issues swinging around from my mirror at the same time as i'm attempting tochronic.

its a convex glass so it brings the entire road or a large area within a seeable view so the images appear coloser

I Personally think You are mistaken... Objects in the mirrors in the car USUALLY seem Farther away than they actully are.

magnification due to bending of the lens that makes it looks near. they magnify it in order to for you to see vehicles even in a far distance.
