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. | ||

HD mapping gives much better than GPS I would imagine. | ||
