Isn't locating near existing transport links essential? How will people get around without having established connections in place already?

Cities operate on quite different economic principles than new towns. Towns are primarily about commuting to and from other locations, making proximity to existing employers and transport crucial. Cities, however, create intra-area employment and activity hubs. They're about pulling people in from surrounding regions rather than sending residents elsewhere. Given the substantial current and latent regional activity in East Anglia and London, the new city would function as a regional hub with its own transport spokes, not just another commuter town dependent on existing links. Secondly the infrastructure economics fundamentally change at city scale. A city of 1 million people creates an overwhelming business case for dedicated rail and motorway connections - the per capita infrastructure costs decline massively compared to smaller developments. While a town of 30-70k might never justify dedicated road and rail links, a city-scale development makes these investments economically viable. We're designing at a scale where the infrastructure investment makes clear financial sense.
