Note that I'm giving my self all of the advantages of all of the alternatives. And I’m also painting this scenario in a world where all of these alternatives have all of the required infrastructure in place[1].

With that said, yes there are faster ways (albeit still less convenient) of getting you outside of said city. You might have to change your mode of transportation a couple of time (I said it was less convenient) but it will still be faster with the right systems and infrastructure in place.

1: This is not an unfair scenario because this is already almost the case for all of the non-alternatives.
