Not wanting to be too nitpicky, but the congestion charge includes the City of London and the West End. The City of London is 1 sq mi (https://en.m.wikipedia.org/wiki/City_of_London) and the congestion charge zone is 8 sq mi total (https://www.autoexpress.co.uk/tips-advice/108908/london-cong...).

I'm not sure how this compares to Manhattan's zone in terms of area.
