When I was a kid, we often used to see wagon chassis, with no body shell. i assume that they were being driven from manufacturer to coach builder. The driver used to sit, exposed to the elements, wrapped up tight in thick, all over clothes, with his eyes protected by goggles. I blame my mother for my belief that these were highly dangerous diseased people and that any contact would be lethal. So they had to move around fully covered, to prevent spread of the disease, but highly visible so that others could avoid them. I think the fresh air might also have been good for them.
