Mass transit is usable as a commute solution. It cannot reasonably replace a car. It can't replace all uses of a car. But what causes rush hour traffic isn't that you sometimes want to go shopping, or that you sometimes stay late at a friend - it's that too many people take the car all the time, and all the way. By making mass transit the default and a car the exception, we'd be a long way towards a solution.
