Earlier quoted context omitted.
I haven't been to Times Square in a while, but I have to assume that's a good example of a busy pedestrian zone in America.
I wouldn't say so. It felt more accidental to me than anything else. Like they just took a place designed for cars, shut the cars out, and yeah it's busy because it's in NYC and there's plenty of density and shops, but the actual urban design itself still felt largely bad and dumb. Maybe it's changed since I've been, though.
NYC was developed in its current form, with high-rises and all, well before cars were commonplace[1].
So no, they didn't take a place designed for cars, and yes, that's why it actually works when you take the cars out of the equation again.
