I always find it surprising when people, imagining some large change, pick on some current reality and how it would have trouble fitting into the imagined future as some sort of indictment of that future. I would suggest that roads closed to most vehicle traffic would be open to delivery trucks, like in most old european town centres, and or delivery is made by smaller vehicles. In the long-term, I can imagine a new model of city infrastructure that allows easy small-scale delivery with some standardized container system and small electric vehicles.
