According to the Stokes' WEB site: "A visual narrative is built up in sequence through the devise of car windscreen wipers, which when wiping enable the viewer to see the road and the developing events in the book ahead. However not well enough to avoid a collision with a motorcyclist. On collision, everything turns upside down and leads to a new sense of time and space floating loose." -- Source of annotation: Marvin or Ruth Sackner.
