Why Egypt Is Building a New Capital City

My gut feel looking at this is that it won't work. Having everything so heavily broken up is just begging for things like traffic problems with unsustainable car dependency.
Walkability, diversity of infrastructure within localised areas, and effective mass transit are so vital to an effective and livable city. Perhaps I may be misjudging how much it has actually been taken into account here, but with the entirely separated park, business, and residential district, it doesn't feel like it has been.
