An interesting question on the Quora-website: are there more black cabs in London or yellow cabs in New York?

There are more in London. As of January 2017 there were exactly 13,587 yellow cabs in New York City. The number of minicabs (private hire or black cars) was estimated at about 60,000.

As of March 2017 there were 21,300 taxi cabs in London.

The number of minicabs (private hire) was estimated at 87,400.

Note that although London taxis (‘hackney carriages’) are usually painted black and are commonly known as ‘black cabs’, it is not actually required for them to be coloured black. (They do have to meet stringent standards of physical design, including being wheelchair-accessible, which gives them a distinctive appearance regardless of colour.) New York yellow cabs, on the other hand, do have to be yellow.
