Foster and Partners’ Masdar City in UAE, is a city designed around walking and driverless cars running on tracks. Think Manhattan with no private cars, only taxis, and computers steering the taxis to increase the road capacity. Then imagine no subway or cycling, only taxis and walking. There is no way such a system could cope with five o’clock knock-off. Can you imagine the queues? Anyway, thanks Foster and Partners for at least guessing.
