An apparatus for finishing a cut edge of a glass laminate includes a support including a surface and an edge, a rail disposed adjacent the support and extending substantially parallel to the edge, a carrier coupled to the rail, and a finishing tool coupled to the carrier and including an abrasive surface positioned adjacent the edge. The carrier is translatable along the rail to translate the abrasive surface relative to the edge. A method includes securing a glass laminate to a support and contacting a cut edge of the glass laminate with an abrasive surface of a finishing tool coupled to a carrier. The carrier is translated along a rail to move the abrasive surface along the cut edge of the glass laminate and transform the cut edge into a finished edge. The glass laminate can have an edge strength of at least about 100 MPa.

A vehicular frameless interior rearview mirror assembly includes a mirror head and a mounting portion. The mirror head includes a mirror reflective element and a mirror casing. The mirror reflective element includes a glass substrate having a planar front side and a planar rear side. No portion of the mirror casing overlaps the planar front side of the glass substrate of the mirror reflective element. A camera is disposed within the mirror casing. With the mounting portion of the mirror assembly mounted at an in-cabin side of a windshield of a vehicle, the camera views a driver of the vehicle, and when the mirror head is moved by the driver of the vehicle to adjust the rearward view provided by the mirror reflective element to the driver, the camera moves in tandem with movement of the mirror head. The camera is part of a driver monitoring system of the vehicle.
