I've heard this before but I'm not sure how it'd work. Would it just be trucks doing deliveries? Wouldn't they still need parking and roads? What's gained by banning the cars if you can't reclaim the roads?
This would still be something like today's yellow zones.

There would be far fewer lanes for the remaining trucks on avenues, and non-avenues could pedestrianized with trucks only allowed to enter if they need to access something on that block.
14th Street is much nicer now that it's only for pedestrians, bikes, buses and local traffic. And for the past few weeks the city has been taking away from cars the west lane on 8th Avenue in midtown (30th to 42nd St, maybe? Basically, from Penn Station to Port Authority, the two local entrances to hell). Something similar is happening near the Javits Center, to give bikes a safer path between the Hudson River and Midtown. Slowly, but it's happening.
Yes
