In Los Angeles County there are more than seven million registered vehicles. Everybody knows about highway traffic here. But where do all those cars go to rest? Gerd Ludwig is a night owl and doesn't need much sleep, so he sometimes goes out at night to photograph "sleeping cars". His chosen cars are loners. They command their own space. They are not crowded in with others to have a presence. After a while he recognises their sleeping patterns. The cars in this project are photographed as he finds them. Their covers are like nightgowns, though some sleep in the nude. Some take daytime naps and a few lucky ones get to sleep together. Occasionally proud car owners ask him if he wants them to move or uncover the car for the photograph, but, Ludwig says, "I generally don't like them to disturb the cars in their sleep".
