You are so wrong on this.
If and object is fixed , as you are saying this is, just a mark on the windscreen it follows by the tenets of perspective that the following
If you move the camera to the right and sightly down, over a succession of images in a short period of time, the static objects will, appear to move,
slightly to the left and up the frame of each picture.
Now i suggest, everyone does this for them self and then make whatever comment they think of the results. I find Irfan is a great little free app for
this as you can open a separate instance of it for each picture and move them round to your own satisfaction.
You can tell, once you open the 3 pictures that Ms Hartigan took 3 pictures within a short space of time, moving the camera either to the right and
down or to the left and up. As i don't know what sequence they were, in fact taken in, try it both ways, the maths is commutative anyway.
Take the 3 pictures taken by Ms Hartigan that do not feature the road. The trees and the street lamp are your fixed objects.
The lay them side by side to each other with the street lamp showing on the right of each picture. You will see that to line up the static objects in
all 3 frames you have to adjust each frame. Fair enough, so it follows does it not? If the object she is claiming is actually a mark on the screen
and nothing more, it will move in a commensurate manner with all the other fixed objects?
Right so if you decide that Ms Hartigan, over the space of the 3 pictures moved to the right and slightly down the smudge should move slightly up and
to the left. it further follows that, the picture that shows the whole of the street lamp compared to the picture that shows just the end of the rays
of the lamp, if it's just a smudge on the glass. The object will have moved considerably to the left of the frame and up towards the top, because, Ms
hartigan has moved the camera to the right and slightly down to show the whole of the street lamp?
So now, you tell me where the *smudge* is having done that?
