The largest number of cars is shipped through the port of Tahara, located in Aichi Prefecture, in Japan,a leading car manufacturer. There are special drivers who move a number of cars to car-transport vessels with remarkable teamwork. They can park cars inside the vessel, while maintaining a 30 centimeter space between them, and a 10 centimeter space on both sides of the car. Car-transport vessels usually anchor at the port only a few days. Drivers must load a total of 4000 cars in 2 days into a vessel, with a 12-storey structure.
