Public transit is going to provide a much larger share of daily commutes, for sure. 

But for it to work, we should be building high density residential/mixed use hubs where bus/tram rides will be shorter than in our current mode, what I call "sprawl and drive," allows.

Seen in terms of the transportation needs of the 21st century,  the McDougal's plan is an anachronism. Worse, it will encourage driving with all the ecological damage and climate change this entails.
