Why do companies make blindspot mirrors that don't give the correct distance of vehicles in the mirrors?

Answer 1

Favourite answer

You should already be used to the distance.

Answer 2

Most people are terrible at judging distance , so what difference would it make. 

If you had a radar device that measured distance and told you “ car in right hand lane is 50m behind you”, most people wouldn’t know if that was safe to pull out or not.  

Answer 3

If it gave the correct distance, then you wouldn't be able to see enough in it, so you would still have a blind spot.

Answer 4

It is due to the convex mirror which although allows a better view, the physics of a convex mirror causes the image to be smaller than reality. It's really there to let you know that someone is there and to turn your head and LOOK!

Answer 5

To allow for a wider distance.
