 About 85 cars pull in. A worker comes by before showtime to clean the windshields, and moviegoers use a special signaling device to get the attention of the carhops when they want to order food. Kadouf put those in to keep people from honking for service. Even though people watch movies inside their cars, the scene here is very social. In front of a row of old Volkswagens, sisters Piera and Zinnia Hoog dance to a soundtrack of 50s rock and roll. They've been coming to the auto kino for years.
