Pees in the brown Koolaid
This is caused by a design flaw.
Above the door of the new cars is a brush that is supposed to keep out the dust.
It is attached to the car with a bright, unpainted aluminum strip that is directly below the camera lens.
This strip reflects any available light, including the red top marker lights, back up into the camera lens which causes the ghost images.
I fixed this problem by putting black electrical tape over the strip. It made a huge improvement in the picture quality.
After peak is over I will ask the mechanic to paint it flat black or brown, but in the meanwhile the tape works just as well.
