> “The trouble is the law. They’ve got no teeth in them. What they should do is make every fourth street an express street cross town and localize it in the afternoon for deliveries. That way you wouldn’t get bottle necks.” Before he could explain “localize” Salit saw a woman walking toward his parked cab.
I imagine that "local" is the negation of "express", as with Subway services. So to localize an express street is to make it not an express street. Perhaps a sensible thing to do in the afternoon, when there is not so much traffic, but a lot of deliveries.
I don't know what he meant by an express street, though!
