Thanks Ben for your comment.
I agree that we face a big challenge in understanding how new technologies will shape the future of transport. All over the World there are new initiatives, sometimes in the informal paratransit sector that can be the seed for your radical change. I agree that mass transit may not be the key factor for transport in the future, as even now it isn't (in many developing countries paratransit services account for two thirds of public transport services). Still, I think the discussion on technology is relevant: First, because it is the governments who bring it to the table. Second, because under certain conditions like high density demand, given that road space is limited, only mass transit systems are efficient.
