A Hansom cab is a type of horse-drawn carriage that was popular in the 19th century. It features two wheels, a covered passenger compartment, and a driver's seat positioned at the front. The design allows for easy access and provides a comfortable ride for passengers. Invented by Joseph Hansom in 1834, the Hansom cab became a common sight in cities like London. It was known for its speed and maneuverability, making it a preferred choice for quick transportation. The cab's design influenced later forms of public transport, including modern taxis.
