Walk in the sky.
The city values pedestrians above automobiles. Literally: above. You can walk for miles on elevated footpaths interconnecting buildings and plazas and gardens, your feet never touching street level. At the same time freeing the cars to be cars.
It could be taken to another level. Again literally: today the walkway system connects second and third stories. It could be expanded vertically to connect rooftops, atria, viewpoints: city planning in true three dimensions, where gardens hang and vines climb and life of all kinds is no longer constrained to the surface of the earth. We do this now in TriadCity, particularly the downtown section of the Southern Third.
