A more point-to-point metro system would be great. The airline industry has been embracing this change for quite awhile. People don't like a hub & spoke system and it doesn't make sense to take everyone to city center which just adds to the crowding and congestion, as many current metro systems do.

Imagine a city that is crisscrossed with multiple direct metro lines. Design for extremely frequent departures, which likely means smaller carriages.

We should be designing our transit systems to be faster and better than car-based travel.
