One has to know that there are trends in urban planning and one of those trends is our current focus on cars being a net-negative to human life and how banning them from cities altogether can only yield net-positives. Clearly this trend is intertwined with the demographic trend of migrating to the urban cores all across the West. So it’s a good thing you‘ve mentioned the Fußgängerzone, which were a trend in the 1950-1970s and German cities adapted them just to find out that they can become a booster of decay, if demographics and economics as well as just the trend don’t hold up (homelessness, empty shopfronts, only elderly folk, unemployed youth hanging around). Fußgängerzonen are largely considered a failed experiment (And because of widespread bombing in WW2 German cities had plenty of room for experiments, which often failed). That they seem to work today, might have more todo with spill over effects from urban population growth, urban revival and a narrow set of datapoints (Fußgängerzonen if plighted areas are often not known to outsiders).
