As a counter example, Vienna largely converted its second major shopping street, Mariahilfer Straße, to a mostly pedestrian + bike zone, with parts of it also shared space with cars, though they do not have priority over pedestrians. Gets very crowded during core shopping hours, so much that biking there is rather difficult. https://upload.wikimedia.org/wikipedia/commons/9/96/Wien_07_...

First one was Kärntner Straße / Graben, which is pedestrians only.

I'm looking forward to more streets getting closed off to cars. Way too much space is reserved for cars already.
