• said second surface of said front substrate and said third surface of said rear substrate opposing each other in said driver-side electrochromic reflective element and with an electrochromic medium disposed therebetween;
• a driver-side specularly reflecting mirror reflector established at a surface of said rear substrate;
• a reflective driver-side perimeter band established around a perimeter border region of said driver-side electrochromic reflective element and visible through said front substrate to a viewer when viewing said driver-side electrochromic reflective element;
• a passenger-side exterior rearview mirror assembly, said passenger-side exterior rearview mirror assembly comprising a passenger-side non-electrochromic reflective element comprising a mirror substrate;
• a passenger-side specularly reflecting mirror reflector established at a surface of said mirror substrate of said passenger-side non-electrochromic reflective element;
• a reflective passenger-side perimeter band established around a perimeter border region of said mirror substrate of said passenger-side non-electrochromic reflective element and visible to a viewer when viewing said passenger-side non-electrochromic reflective element;
• and
• said passenger-side non-electrochromic reflective element exhibiting an appearance of said passenger-side perimeter band that generally matches the appearance of said driver-side perimeter band of said driver-side electrochromic reflective element when both are mounted on the vehicle and viewed by a person viewing the respective reflective elements of said passenger-side exterior rearview mirror assembly and said driver-side exterior rearview mirror assembly.

A rearview mirror assembly for a vehicle, said rearview mirror assembly comprising:

• a transflective mirror element having a front surface and a rear surface;
• a video display screen disposed behind said transflective mirror element, wherein said video display screen is operable to emit light when actuated and wherein the light emitted by said video display screen is visible through said transflective mirror element when said rearview mirror assembly is viewed by a person viewing said rearview mirror assembly;
• contrast enhancement means for enhancing the viewability of said video display screen when said rearview mirror assembly is operated in high ambient lighting conditions;
• and
• wherein said rearview mirror assembly comprises an interior rearview mirror assembly, and wherein said transflective mirror element comprises a wedge-shaped prismatic mirror element, and wherein said video display screen is mounted at an angle relative to said rear surface so as to reduce potential ghosting due to the angle of said front surface of said wedge-shaped prismatic mirror element relative to said rear surface of said wedge-shaped prismatic mirror element.

A driver attitude detection system for a vehicle said driver attitude detection system comprising:

• a sensing device for sensing at least one driver characteristic;
• a vehicle monitoring device for monitoring at least one vehicle characteristic, said at least one vehicle characteristic, said vehicle characteristic comprising at least one of (a) vehicle seed (b) a vehicle acceleration, (c) a vehicle orientation and (c) a vehicle maneuver;
