The camera tracks downwards and slowly but clearly picks out a speeding navy blue BMW. When the BMW is very near, below the camera - stop frame. Silence. This lasts a second, enough to see - out of focus - a fragment of a man’s face at the steering wheel, a woman, also out of focus, laughing at his side, and the outline of a child’s face between them in the back. After a second, this image moves, more cars drive past.
