What is the appropriate angle for the right rearview mirror to tilt downward?

[DelNadia]

The appropriate angle for the right rearview mirror to tilt downward is 27 degrees. Function of automatic rearview mirror tilt during reversing: Automatic rearview mirror tilt when reversing refers to the right rearview mirror automatically adjusting its angle downward when the vehicle is shifted into R gear, making it easier for the driver to see the ground conditions. Vehicles with memory function seats usually have this feature, though the setup method may vary depending on the car model. Car mirrors are convex mirrors: They provide drivers with a broader rearview range, helping them observe a wider surrounding environment and thus enhancing driving safety. The side mirrors on cars are typically convex mirrors with a spherical surface and varying radii of curvature. The reflected image is smaller than the actual view but covers a larger field of vision. Convex mirrors produce an upright, reduced virtual image, allowing a wider view compared to a flat mirror of the same size. That's why the exterior mirrors on cars are convex, giving drivers a broader view when reversing, which increases safety by reducing the chance of hitting people or objects.
