You're making a subjective judgment and stating it as a fact.<p>Most cities wouldn't be able to function if you hard to park a car for every workday commuter.  Especially Boston, I used to live there, you telling me there's room between the South End and Beacon Hill for all the people that work there?  Maybe if you paved the commons and turned it into a 5-level garage.  Sounds lovely.  And that's not even getting into what it costs to pay welfare and housing for all the people who would no longer be able to hold a job without a way to get there (not as big a deal in Boston since the subway barely goes to Dot and Roxbury as it is - they're on the bus anyways).
