I think self driving cars might make public transport much more viable, by increasing the effective range of stations. An entire sprawling suburb could be served by a single station, with people taking self-driving taxi rides from their doorstep (timed to allow a short transfer) and then getting in another taxi to get to their destination. It would be almost as convenient, but people wouldn't be wasting tonnes of road space for the bulk of their journey. A service like Uber (or possibly Google maps) could even offer integrated tickets for the whole journey.
