why do they put convex mirrors on cars?

Question

A long time ago the mirror on the passenger side of the car was a standard rear view mirror, Now they've changed it so that it does not give a true image.

Answer 1

Gives a larger field of view. I like the old ones better myself.

Answer 2

It's a lousy attempt to eliminate blind-spots in the drivers field of vision.

Answer 3

exactly what he said, you can see more with the convex lenses, even if it does change the size of objects you see in it
