How's that? If you live in NYC, you get paid more. People who live in NYC have the amongst the lowest carbon footprint in the nation. If you live in a dense urban area, you generally will have a lower carbon footprint.
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.
