I'm not aware of another city in the USA with as useful a transit system. In terms of what it could be, it's atrocious. In terms of how it enables the city to function, it's essential.

Come to SF then you will think nyc transit is quite strong in fact

Name a single city in the US that has a better one.

NYC doesn't compare to Europe or Asia, of course, but it's streets ahead of anything else in the US.

*Note: there is SO MUCH wrong with the MTA and the NYC subway system, but it's currently the best in the country, unfortunately.
