... And you think it bears some resemblance to reality?
The view on the left is taken in my Sketchup model viewed from close to the car on Zapruder's sightline, so the front of the car appears closer to the viewer than the rear of the car. Zapruder was using a zoom lens from about 120 feet away so the difference in distance from the viewer to the front and to the rear is not as much. So the perspective and angles appear different. You better than anyone should understand that.
Here is the view from Zapruder's position:
Here is a view along the same sightline from up close - a few feet away from the front bumper.
It is the same drawing with the same trajectory angle. Nothing has changed except the position of the viewer along the sightline from Zapruder.
