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 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 having to carry smaller mirror elements. <EOS>
