[citation][nom]ssalim[/nom]I don't get it, what is this for? so driver needs to look then read what's in the mirror? that's going to cause crashes.Mirror is just for quick checks, not reading or analysis.[/citation]
You don't have to write information, ever heard of visual information.
If when you look to the rear view mirror see a red halo (e.g.) around an aproaching car this will informe you quicker and better than regular mirror...
that's my "view" of this subject
