Indeed, the City is vast, and what people refer to as Greater Los Angeles—which includes most of the grey areas on the first map, like my hometown of Glendale, and a ton more to the east not displayed—is still more vast.

Greater LA aside, there's no chance in hell they lay fiber to every residence in the Valley (the communities that the 134/101 run through and everything else north of that), there's no chance in hell they lay fiber all the way down to San Pedro. Not for five billion dollars, not for five trillion dollars.

Anyone who has so much as casually observed an LA infrastructure/works project in recent history knows that this ends in tears.
