The Black Cab represents "The Knowledge"—the deep, internal mapping of your own life path. It suggests that while the route may be complex, there is a reliable internal guide who knows every street and shortcut.
Spiritual Significance
It symbolizes the "Hermit" or the "Guide" who navigates the fog of the city. It represents a paid or earned transit through a difficult emotional landscape.
Psychological Perspective
The shadow is "Blind Trust." Are you the driver or the passenger? If you are in the back, you are relying on someone else's "knowledge" to get you where you need to go.
