Vast majority of space, especially around the Manhattan and the dense part of Brooklyn and Bronx already is commercial unloading only Mon-Fri, yet the dynamic I mentioned is common place. Again high density implies shortage of space - you want groceries and bike/car lanes, but only get to pick one of the two.

It is possible to get groceries without a car in New York.

You are really ignoring the huge opportunity cost of land that is widespread personal car use in NYC - people just tend to ignore how much land that really is because they are so used to it*. Delivery trucks wouldn't be a problem if there were a lot less cars, but cars are sarcosanct in America.

[*] The story of the original Sim City comes to mind. They originally were going to show parking lots, etc, but realized all this infrastructure actually made it look stupid and empty.

Well of course it is, either a delivery truck unloads it to your local bodega, or an an amazon car unloads it to your doorstep. Again during the workweek, vast majority of street parking is only open to those two options, yet double parking is common place.

> already is commercial unloading only Mon-Fri

I’m aware. That’s why people are advocating enforcing the law.
