Either I have a very different idea of what London's "City Centre" is, or the numbers above for London look quite low. That said, for some people, Zone 4 is "central" and for others only Zone 1 is. Curious how the SF numbers compare in this regard.

Traditionally Zone 1-2 is central.

Anyone who calls Zone 4 central is deluded.
