Longer trip equals more money for driver
It would seem that most taxis are cashing in on routes around the city, which is the classic scenario: we are shopping and we want to go home, and unfortunately public transport will not come for another hour. What we do? We call for a taxi and in a few minutes we're going home. What is interesting with such courses taxi drivers do not earn much, the majority goes to fixed costs and fuel.
Intercity routes or airport transportation is the most profitable routes for the taxi driver and transport companies. The more such routes during the month, the better for the driver. Shorter routes is more filling and the way to the taxi does not stay for all day long.
Is taxi that expencive
In every major city we have a choice about the means of transport. You may for example use the public transport, train, or at least your own car. You may even order a taxi, but some people say they are too expensive, so do not even take them into consideration.
However, the taxi is a convenient way carrier to long journeys. Most of them are equipped with air conditioning and other amenities, so the ride even in the sweltering heat is not exhausting. As for the cost of a taxi ride you can argue whether it is expensive or not. It must be remembered that the cab driver still has to get back to their city after completing the course.
Wikipedia about taxicab
A taxicab, also known as a taxi or a cab, is a type of vehicle for hire with a driver, used by a single passenger or small group of passengers, often for a non-shared ride. A taxicab conveys passengers between locations of their choice. This differs from other modes of public transport where the pick-up and drop-off locations are determined by the service provider, not by the passenger, although demand responsive transport and share taxis provide a hybrid bus/taxi mode.
