1. A vehicular interior rearview mirror assembly, the vehicular interior rearview mirror assembly comprising:
a mirror head comprising a mirror casing and a mirror reflective element;
a mounting assembly configured to mount at an interior portion of a vehicle equipped with the vehicular interior rearview mirror assembly, wherein the mirror head is adjustable relative to the mounting assembly via a pivot joint;
wherein the mirror casing comprises a sidewall having a wall thickness spanning between an inner surface of the sidewall and an outer surface of the sidewall;
wherein the sidewall comprises an outer end region that circumscribes an open portion of the mirror casing;
wherein the outer end region of the sidewall comprises a rounded outer surface curving between the open portion of the mirror casing and a less-curved outer surface of the sidewall;
wherein the mirror reflective element is disposed at the outer end region of the sidewall at the open portion of the mirror casing;
wherein the mirror reflective element comprises at least a first glass substrate, and wherein the first glass substrate has a front surface and a rear surface and a substrate thickness spanning between the front surface of the first glass substrate and the rear surface of the first glass substrate;
wherein, with the mounting assembly mounted at the interior portion of the vehicle, the front surface is closer than the rear surface to a driver of the vehicle who is operating the vehicle;
wherein the first glass substrate comprises a flat region at the front surface and a rounded perimeter edge circumscribing the flat region and extending between the flat region and the rear surface;
wherein the rounded perimeter edge of the first glass substrate has a first radius of curvature of at least 2.5 mm, and wherein the substrate thickness of the first glass substrate is less than 2 mm;
wherein, with the mounting assembly mounted at the interior portion of the vehicle, the rounded perimeter edge of the first glass substrate is contactable by and is viewable by the driver of the vehicle;
wherein curvature of the rounded outer surface of the outer end region of the sidewall matches curvature of the rounded perimeter edge of the first glass substrate; and
wherein the rounded outside surface of the outer end region of the sidewall and the rounded perimeter edge of the first glass substrate combine to provide a curved transition between the flat region at the front surface of the first glass substrate and the less-curved outer surface of the sidewall of the mirror casing; and
wherein a circuit element is disposed in the mirror casing, and wherein the circuit element comprises a planar substrate and supports circuitry thereon, and wherein a plane of the planar substrate of the circuit element is non-parallel to a plane of the rear surface of the first glass substrate.
