A set of rear view assemblies for a vehicle comprising: - a first rear view assembly to be mounted to a driver side of the vehicle to observe traffic conditions behind on the driver side, comprising a first base assembly and a first head assembly mounted on the first base assembly, and - a second rear view assembly to be mounted on a passenger side of the vehicle to observe traffic conditions behind on the passenger side,, and - a vision system at least comprising a vision sensor and a display, wherein the first rear view assembly and the second rear view assembly are exterior rear view assemblies, and the first head assembly comprises a mirror element having a minimum size still fulfilling the legal requirements provided for a mirror-based field of view (FOV-21) on the driver side, and the second rear view assembly comprises a second base assembly and a second head assembly mounted on the second base assembly, characterized in that the second head assembly comprises a mirror element having the same minimum size as the one of the first head assembly of the first rear view assembly, and the vision sensor is arranged in the second rear view assembly to record an image of the traffic conditions behind on the passenger side to be displayed to a driver by the display with a field of view adapted to meet the legal requirements for the mirror-based field of view (FOV-22) on the passenger side regardless on the reduced size of the second head assembly of the second rear view assembly, with the legal requirements for the mirror-based field of view (FOV-22) on the passenger side being larger than the legal requirements for the mirror-based field of view (FOV-21) on the driver side, wherein the first rear view assembly on the driver side and the symmetrical second rear view assembly on the passenger side are reduced to a size adapted to the smaller field of view (FOV-21) on the driver side resulting in smaller rear view assemblies (1, 2) having to carry smaller mirror elements. - a first rear view assembly to be mounted to a driver side of the vehicle to observe traffic conditions behind on the driver side, comprising a first base assembly and a first head assembly mounted on the first base assembly, and - a second rear view assembly to be mounted on a passenger side of the vehicle to observe traffic conditions behind on the passenger side,, and - a vision system at least comprising a vision sensor and a display, the first rear view assembly and the second rear view assembly are exterior rear view assemblies, and the first head assembly comprises a mirror element having a minimum size still fulfilling the legal requirements provided for a mirror-based field of view (FOV-21) on the driver side, and the second rear view assembly comprises a second base assembly and a second head assembly mounted on the second base assembly, characterized in that the second head assembly comprises a mirror element having the same minimum size as the one of the first head assembly of the first rear view assembly, and the vision sensor is arranged in the second rear view assembly to record an image of the traffic conditions behind on the passenger side to be displayed to a driver by the display with a field of view adapted to meet the legal requirements for the mirror-based field of view (FOV-22) on the passenger side regardless on the reduced size of the second head assembly of the second rear view assembly, with the legal requirements for the mirror-based field of view (FOV-22) on the passenger side being larger than the legal requirements for the mirror-based field of view (FOV-21) on the driver side, wherein the first rear view assembly on the driver side and the symmetrical second rear view assembly on the passenger side are reduced to a size adapted to the smaller field of view (FOV-21) on the driver side resulting in smaller rear view assemblies (1, 2) having to carry smaller mirror elements.
