In many cities not only are the streets not designed but everything about the city seems as if no intelligence at all was every applied to designing much of anything. What we really see in cities is an elderly quagmire to which additions upon additions are heaped into the web creating an ever worse situation. Whether it is a tiny box of candy or a huge new sofa it is overwhelmingly obvious that one would need space for deliveries to be accommodated even when a horse drawn wagon arrived with that sofa. The sins of local planners will be visited upon their children even for ten or more generations. So for apartment houses let drones deliver to the roofs or courtyards and for homes let a flag pole like platform be built that has a feature for lowering the received package down to ground level. But really, the major answer is to destruct our older cities, lay out new plans and start over. Just imagine how many new jobs we could create if we leveled Brooklyn and redesigned and rebuilt from the ground up, and how much more sane the place could be. Then there is Chicago or Baltimore or any number of places just begging to be plowed down and redone.
