When people think of London and the United Kingdom, sometimes they think of the stubby looking taxi cabs that are driven along the streets.
The UK is famous for their taxi service particularly because taxis are regulated to ensure that the cars and the drivers meet a certain standard. The regulation of taxi cabs is particularly evident in London where there are strict rules over the mechanical functioning of the taxi cabs and their is monitoring over the extent of the taxi driver's knowledge. While there are a number of rigorous regulations, these regulations are mostly known by the taxi drivers of London, whereas everyday people outside of the trade typically are unaware of them.
The regulations are useful for passengers to give them a greater sense of trust towards the taxi service of the UK.
