Yellow taxi cab moving across the bridge and huge buildings in the background.
The young couple in the taxi are a bit afraid going over the 4 mile long bridge.
The taxi does not necessarily have a young couple in it, they were not necessarily a bit afraid, and the bridge was not necessarily 4 miles long.
