The majority of the population lives in urban and suburban areas, and a minority lives in rural areas. These are very different environments and public transport should be expected to be very different between them. In cities, we should expect a high capacity system, like subways, 10-minutes buses and trams. Gradually, as we move outside the cities densest areas, we should have a lighter but faster system, such as light transit rails, longer but still frequent bus routes. Eventually, as we move outside suburban areas into rural areas, we should get something that barely exist right now: on-demand transit, like collective taxis, or flexible minibuses.
