There are no such things as blind spots, just badly adjusted mirrors.

The Red lines are how most people have their cars set up. The "side view" mirrors then only show barely any more information than the center rear view mirror. The Cyan lines are set up based on
this 1995 SAE paper by a person named George Platzer. When the mirrors are Platzer-ized, they form one big mirror with information spread out with minimal overlap between mirrors. The Red Car which is in the traditional "blind spot" would be perfectly visible in the "new" setup. When the Red car is starting to leave the side view mirror, it enters the drivers actual field of vision forward from the B pillar.
The image could use a bit more overlap to eliminate the very small blind spot while still expanding awareness of the ex-blind spot.
