 | | Originally, hackney carriage companies were distinguished from each other by their drivers' livery (uniforms) and by the colours of their carriages. |
 | | Black cabs--also known as hackney carriages, or hackney cabs--are particularly famous on account of the specially constructed vehicles and the extensive training course ("The Knowledge") required for fully licensed drivers; unlike many other cities, the number of taxi drivers is not limited. |
 | | London's cab drivers are even well-known for having developed an especially big hippocampus, a region of the brain where, among other things, information about locations is stored (this is likely the case with many other taxi drivers, as well--not just those of London). |
