Major cities are packed with parking decks, but decks are expensive, so they’ll only be built if land values are high. For most of America’s history it was simply cheaper to build out than up in most places.
It may be ugly, inconvenient, and environmentally problematic, but it shouldn’t be confusing.
Edit: it occurs to me that more parking, decks or otherwise, would actually be good for cars which seems antithetical to the point of this community… so I’m unsure what point is even trying to be made aside from calling America stupid
