I can't see bikes taking over in urban area with actual climate. Even the biggest enthusiasts in Chicago or New York will tell you it sucks during the winter.

And I can't see mass transit being viable when our biggest cities with the money and initiative to improve it plan these projects over the scale of decades and billions per mile.

Self driving cars or trolleys on the existing road surface is probably the most realistic form of mass transit out there. We have the vehicles and the infrastructure already.

It doesn't have to be self driving at first either. Uber's forays into mass transit with shared rides and fixed pickup locations was always pretty solid for me and reasonably priced.
