  That's great for going between cities, but useless within them. It also needs something on a smaller scale for people to get from home to work to the shops to home without standing for 30 minutes in the rain and not getting a seat, or for them to get home when drunk at 3am and the trains don't start until 6.

    Self-driving cars could be very economically feasible for traveling within a city. They will be able to drive in tightly packed formations to minimize air resistance as well...a sort of hybrid between public transportation and individual/family transportation.
