Have you ever been to NYC? Manhattan, specifically? During rush hour? I'm not sure if you're starting to make a market-based Rational-Man-type argument, but I'll cut you off and say: you don't have a choice BUT take public transportation, unless you can afford to take a helicopter and live and work right near helipads. Even an Uber/taxi can be an impossible nightmare time-wise during rush-hour. Most people who commute in on the NJT/Amtrak (the topic of the parent submission) don't have the choice to take a car or walk. The NY Metropolitan area is not the rest of the United States. The population density is like nothing else.
