It's worth it to you to trade distance for clean/quiet, but it's the companies involved using the trucks that need to be convinced. Telling them that they need to have separate trucks for city use and long haul use will receive push back from sheer momentum of how it's done now. Unless the cities get involved and tax the bejeebus out of them for not switching, they will never switch.

They already often have very large trucks that only go to warehouses, and would be a pain to drive through a city, especially such an old and super-dense one as NYC.

Smaller trucks move smaller quantities around the city from the warehouses.

Maybe sometimes you need to bring something especially large e.g. for a construction; such deliveries may be special-cased and planned carefully, instead of being completely off-limits.

It's not the companies that need to be convinced, it's a matter of the people wanting this enough that politicians act on it or get voted out, and then companies are just forced to follow the regulations that require such trucks.

The US is a democracy that doesn't act like one.
