What good jobs do drivers in Shanghai dock have to move cars?

Very good. Because the dock driver's job is very simple, after a foreign ro-ro ship full of imported cars stops at the dock every day, he will board the ship, unload the imported cars and send them to the yard. For the export of domestic cars, he will put them on board, then load them on ro-ro ships with ocean-going cars, and send motor vehicles made in China to ports and docks all over the world. It's such a short distance to go back and forth, and the work is easier.
