Wikipedia and hybrid taxi
Hybrid taxi or hybrid electric taxi is a taxicab service provided with a hybrid electric car (HEV), which combines a conventional internal combustion engine propulsion system with an electric propulsion system.
In 2000, North America's first hybrid taxi was put into service in Vancouver, British Columbia, operating a 2001 Toyota Prius which traveled over 332,000 kilometres (206,000 mi) before being retired. Several major cities in the world are adding hybrid taxis to their taxicab fleets, led by San Francisco where hybrid represent almost 50% of its taxicab fleet by March 2010, and New York City where hybrids taxis represent 45% of the city's total fleet by September 2012. Unlike conventional gasoline cars, hybrids get better fuel economy, do well at slow speeds or idling, and have cleaner emissions.

Wikipedia explains what is "London taxi"
The Beardmore was an alternative taxi design used in London during the 1960s and 1970s
Until the late 1950s, vehicles licensed as London taxis were required to be provided with an open-access luggage platform in place of the front passenger seat found on other passenger cars (including taxis licensed for use in other British cities).
A hackney or hackney carriage (also called a cab, black cab, hack or London taxi) is a carriage or automobile for hire. A hackney of a more expensive or high class was called a remise.

Methods of transport
Personal transportation comes in many forms, from the trains, the buses, on taxis and cars ending. Private transport companies grow more and more because of the increasing demand for transport services relating to the carriage of passengers.
More and more customers want to get to the specified place, so no longer use public transport (trains and buses) because most of them choose the taxi and transportation such as Uber. But taxi companies have quite competition in market, so they must develop a way to keep their customers beside them.
