NYC is the absolute best case in the US, if you're talking about the ability to exist without a car. It's not that no one talks about those millions of households, it's that they are all concentrated on a few standout islands (literally!) in a sea of the nearly identical car-only supermajority of cities. It's the exception to all exceptions.
Most people live on a few islands of density in a sea of nearly empty land in the US.
