So the driver with a mirror at A would not be able to observe a motorcycle at C but a camera mounted at B would?Cameras don't need to be as wide out as a mirror for the same view.
What you aren't telling us is that for the light to bend around the corner of the trailer there has to be a tremendous mass (about like Jupiter's) in the back of the trailer (General Theory). I think this would adversely effect towing range.
It doesn't matter whether the objects at A and B are curved mirrors, flat mirrors or the Hubble telescope. No light traveling in a straight line from anywhere in the shaded triangle can reach them. This should be intuitively obvious but if it isn't go sit in your car for a few minutes. Most have a flat mirror on the driver side and a curved one on the passenger side. Can you see an object located at X?This is why a curved mirror doesn't need to be as far out as a flat mirror.
No!!! Light travels in straight lines except in extremely intense gravitational fields or where the refractive index of the medium changes along the propagation path. In a camera lens the rays are refracted at places where there are discontinuities in refractive index but they remain rays (i.e. travel in straight lines). Lenses are designed using "ray tracing".The path for a camera is curved (wide angle lens).
