Yeah, though I think Bay Area is similar - LA is huge and more equivalent to compare to Bay Area (SF + Oakland + Peninsula + San Jose), than just SF itself.
To be clear; what I mean LA as in LA city not the county. LA and Miami are similar in they have some neighborhoods that are walkable (the most popular parts), but the majority of them are not and they’re not very walkable between the two. Little Tokyo is walkable but then there’s a gap between there and downtown, then you have a huge Hollywood stretch then a huge gap around ktown if you go between them. Miami has the same issue, Brickell is walkable but as soon as you leave it has a bunch of impassable areas to go to downtown, same as if you were to leave wynwood. The worst part of Miami city’s unwalkability is once you leave those neighborhoods it pedestrian hostile like Shendahdoah or Little Havana.
SF and NYC do have neighborhoods like this, but those occupy very tiny portions of those cities comparably to Miami.
