Several users have reported problems with darkened review mirrors when backing up in a dark environment. Typically backing into/out of their driveway when lamps are disturbing the mirror causes it to be hard to see what’s going on around the car. An option to disabling the darkening of the mirror while backing up should be part of the settings.
In Europe, turning the rear fog light on while backing up might also improve rear visibility.
Implemented with v10 software and vehicles with HW2.5 or later by showing the rear and side cameras on the center screen.
Could make this item more general, for instance: "Improve visibility when reversing in low light conditions". Other improvements could for instance include turning fog light on when "R" is engaged, and/or increasing the brightness of the lights that come on during reverse driving.
