Taxis are very useful if you live in the city. How many times a month you happen to use the services of taxi transport? I suspect that at least several times a month, and many people use these services couple times a week.
It is worth considering why choose a Taxi- yet we have buses and metro. What makes the taxi is more convenient and better in some situations? I think it is a matter of getting on to it when and where you want and that you get exactly to the indicated address. This is luxury that you won't get in public transport.
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.
Forms of personal 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.
