You will be able to summon an autonomous taxicab (AT) using your smart phone, and direct it to leave you at your desired location, at a cost that is about a third of current taxi fares and thus comparable to the user cost of public transit. (AT services will normally not need government subsidy.)

However, an AT service would be a form of public transit and thus public transit may be considered due for major expansion, albeit in a very different form from what we have now.
