I could write a novel about this subject (and trust me, I will, especially if Albany doesn’t pass an MTA bailout), but I’d rather sum it up with the masthead of San Francisco’s MTA website:
If all of these issues were handled by one agency in New York City, the city could have a world-class transportation system. Instead, these issues are managed by many separate agencies and city departments that rarely, if ever, work together, unless there’s a harebrained scheme to add a taxi surcharge and send half of the revenue out of the city.
San Francisco has a lot of its own mobility issues (including its own budget deficit), but New York could cut out a lot of bureaucracy if it adopted their model. That is, if Albany would ever let them.
