I'm imagining a concrete mixing truck filled with dough, feeding into another truck with an oven with rollers. The dough gets piped into the truck, formed into a tube of dough, rolls through the oven, and extruded from the truck as bread. One of those big Drs office paper rolls is hooked to the bumper to make a barrier between the pavement and the bread.
