Most people living in NJ but working in NYC are taking trains or buses into the city, so the marginal carbon footprint there isn't as big as you might think. There's only a couple suitable river crossings for this commute and they're already facing hour-long delays during commuting hours, so there's no room to add more cars commuting into NYC (nor anywhere for them to park in NYC anyway). Fortunately these river crossings have dedicated bus lanes during rush hour, which move more people than all the other lanes combined.
