The mirror consists of a small proximal part and a large distal part, having a size ratio of approximately 1 : 2. Figure 2 shows that the angle between the parts is ± 4 - 12 °... In order to eliminate the blind spot, conventional rear view mirrors of cars are frequently provided with a small convex portion distally. Sometimes a separate small-sized mirror, which forms an angle with the main mirror, is attached to the distal portion of the mirror. Unfortunately, these constructions do not solve the problem of the blind spot adequately: because the distance between the convex distal portion of the mirror and the overtaking vehicle is relatively short, the image of the vehicle in the mirror is large and it also runs through the mirror very rapidly. Another solution is tried in shaping the mirror surface in a convex manner; this however may create difficulties in the estimation of the distance between the mirror and the overtaking vehicle... Quite a number of commercial vehicles are..
