What Would NYC Be Like Without The Subway?

After reading the NY Times article linked to from Brownstoner regarding Gov. Paterson's decisive rejection of another save-MTA plan, I thought how dystopian would it be if we didn't have the subways. The whole debacle on the A train in Brooklyn from Jay St. to Euclid including some weird shuttle bussing and lots of yelling got me thinking too. Walking and biking would of course increase but it'd be a pretty interesting character study fodder for a movie eh? Like Do The Right Thing, but instead it'll be called "Insufficient Fare" or something...
