Integrated transport system
Gimme an app. I tell it where I am, where I wanna go to and it gives me a choice about how I get there, the time it take and at what cost. e.g Pick me up in a driverless car, take me to the train station, the app has booked my train ticket. at the destination train station another driverless car is waiting to take me to my final destination. If there's a problem, traffic jam, cancelled train etc, the app reroutes in realtime, gives me other choices and costs and we can chose one of those. At the end of journey it gives me one bill.
