I used the term Greater London to try to make the distinction. I failed you.
Since the toll and comparative congestion pricing are municipal concepts, the arbitrary sizes matter for the purposes of figuring out consequence. The post was not very illustrative, since I compared LA to London, as opposed to NYC to London. The greater LA area just happens to share arbitrary terminology to my choice of description, rather than specific relevancy.
timr is not correct, he is confidently wrong even if he makes the same claim several times in the discussion.
And you keep forgetting to say that London is 600 square miles, and Manhattan is about 20. They're also vastly different in terms of their connectivity to the outside world. The "London congestion area" is a tiny section of the middle of London. This covers almost every major ingress/egress into the island of Manhattan.
> The City of London, London's ancient core and financial centre − an area of just 1.12 square miles (2.9 km2) and colloquially known as the Square Mile − retains boundaries that closely follow its medieval limits.
Greater London, in total, is larger than Los Angeles.

The congestion charge is not for Greater London and the Manhattan toll is not for all of Manhattan.
