Close to
5 million people ride MTA trains and buses every day. And that number gets much higher if you include commuter rail, NJ Transit, PATH, ferries etc. operating in the city. Over 70% of daily commuters in NYC already use some form of public transit, and
90% of those commuting into Manhattan use public transit.
All the "the subways are too crime ridden to use" shouts are pure propaganda. If millions of New Yorkers can survive, so can you.
