I think that other big cities that are progressively closing to cars have it right. If I look at paris, it already has a very dense subway system. The main drawback is that it closes between midnight and early morning and that it could be even denser. Close the roads to cars (except emergencies and buses), promote bikes and electric longboards (along with other transportation systems that are easy to carry under your arm when you are done) and you have a solution for megalopolis.
