Gerd Ludwig explains in the introduction to Sleeping Cars (Edition Lammmerhuber, 2016), My cars are loners. They command their own space and enjoy showing off their presence. Like a devoted bird watcher I have learned to recognize their sleeping patterns. With voyeuristic pleasure I've spied on them in their nightgowns. I've watched some sleep in the nude; some take afternoon naps and a few lucky ones get to sleep together. I find covered cars more in L.A. than anywhere else. Here, middle-class families generally own more than one car, but their homes only have one-car garages. So many cars are left parked on the street for an extended period lovingly covered, especially during holidays, when their owners treat them like crated pets.
