Not every car can become a taxi
Taxis are often middle-class vehicles, usually having air-conditioning, leather seats and other amenities. Most often evokes car brand associated with the taxi is a Mercedes, because it is regarded as the most reliable car manufacturer.
A taxi must be comfortable - so middle class or high. I can not imagine that a taxi could be a car hatchback or van. The air conditioning is absolutely essential, especially on hot days, which is recently more and more. As for the leather seats they are easy to clean and disinfect, and the cleanliness of the taxi is as important as comfort.
Quote form Wikipedia about Hackney carriage
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.
How to plan trip abroad
Traveling abroad, especially transport, when we get there, can be very problematic. It is therefore important to plan everything, including how to get to the hotel from the airport, or how we drive between airports if necessary.
That's all you can plan his desk in preparation for departure. Transport companies and those offering airport transfers have their own websites through which foreign visitors can submit inquiries and orders. In this way, we will not have to worry about anything during the trip.
