NYC is also one of the most regularly built out cities, in stark contrast to Boston, for instance. OTOH roads here may be 3 or even 4 levels high at the same point (e.g. where Manhattan bridge meets Brooklyn), and GPS is sometimes way off in canyons between skyscrapers.

And here I thought Chicago was complex with lower lower Wacker (just 3 levels).

This is probably very challenging for human drivers using navigation, but probably no nearly as much of a problem for a Waymo car with onboard 3D maps of the entire operating area.

HD mapping gives much better than GPS I would imagine.
