To duplicate the capacity of the trains, you'd need enormous amounts of parking and bridges. Someone crunched the numbers and found you'd need a parking lot the size of Manhattan and at least two layers deep to accommodate all of the commuters if they drove, as well as 48 additional 8 lane bridges. https://mtayloranalysis.wordpress.com/2014/12/09/an-auto-oriented-manhattan/ https://mtayloranalysis.wordpress.com/2014/12/09/an-auto-ori...

Right, but with a self-driving taxi system you don't need a discrete car per person that's only used for transit in and out of the city. You can use fewer and reuse them over and over and over again during the course of a day. This is both a more flexible and more robust system than trains. Plus, given a grid system like Manhattan, blockages can be routed around. People don't seem to believe me, but we're all on the internet aren't we?
