        Why? Because when one focuses on an inner portion of the movie, the optic flow angular speed is slow, and appears to fill one’s entitle visual field, which is consistent with overall lower forward speed.

        Note: The more zoomed, the more densely packed the overhead rigging appears. So, even though you appear to be moving forward more slowly when zoomed in, the actual rate of rigging flowing by remains constant, consistent with same forward speed in all conditions.
