London is 600 square miles and has numerous routes into and out of the city. Manhattan is 23, and is an island with a handful of bridges and tunnels.
As a percentage of the whole, the City of London is trivial, whereas this "congestion district" is about half of Manhattan (even more if you account for central park).
