How do you expect to create "healthy, livable cities" at a time when cities are in decline, perhaps even becoming obsolete? First, the internet killed physical retail, recently, the pandemic killed more businesses/opportunities and caused an exodus of WFH-ers, and in some cities there's a very visible rise in crime, drugs, and homelessness.
Removing private cars from cities won't revolutionise them, when the roads are still going to be full of commercial vehicles, buses, and taxis. Yeah, it'll make it somewhat safer for cyclists and reduce air pollution and noise a little - but not enough to turn a declining urban dystopia into a desirable place to live.
Unless of course, you're very wealthy and can live in a luxury apartment with good security and plenty of distance from the 'rough areas'.
