Driverless cars also means that taxis can be scaled a lot more according to real time demand. Unlike taxi drivers who have to work on a x hour shift, on demand driverless taxi can start and stop working at any time. Second, if people can call a taxi using a smart phone app then taxi's don't need to wondering around the city without passengers. These two factors combined will further dramatically lower the cost for taxi more, a lot more than the 2 thirds cost cut down this article predicted (http://www.theglobeandmail.com/report-on-business/economy/economy-lab/why-the-future-of-urban-transit-might-be-a-taxi/article6764554/ http://www.theglobeandmail.com/report-on-business/economy/ec...). The cost (and effort required) of using such taxis as main means for transportation will be significantly lower than owning a car even without the concerns of parking expense (in rural areas). Does that mean that cities will further spread out or the other way? Who knows. I think it means more freedom for people to select wherever they want to live. You can live in the middle of Manhattan without worrying how to get to the countryside with your dog. You can also live in the mountain and commute 5 hours a day to Manhattan to work (because that 5 hours won't be lost in driving any more)
