Почему такси в Англии темное ?

London taxi is not just a transportation service, as is customary in many countries, consisting of random transport of all stripes and its drivers. It has its own culture, glorious history and national traditions. The world-famous black cab is one of the business cards of the English capital. The history of Londons taxi dates back to 1639, and it was the first time, coaches in the Corporation joined the Corporation and agreed on licensing truck services.
The tradition to paint all English taxis in black existed until the 80s of the last century. It is explained by the desire of manufacturers to save on automotive enamel (another interpretation leads Henry Fords catch phrase, which said that a car can be of any color if it is black). Today, London taxis are not only painted in different colors, but also carry bright advertising on the sides.
