I live in one of the major metro areas of Florida, and even here public transport is abysmal. We have a single train line that goes north south about 30-50 miles. And a few buses that basically ferry the homeless around all day while they sleep on it.

That's it.

1) The US is not structurally capable of building public transit. For suburban areas like this, light rail is workable. But it costs us as much to build light rail as it costs other countries to build fully underground automated subway systems.

2) These are suburbs, so there is no rhyme or reason to where things might be located. It can literally take hours to do a route that you could do in a car in 30 minutes.

Look close - that form factor doesn't leave any place for transit to run. Most things would be a long way from any stop/station. The density would support a line every 2000 meters with stops 800 meters apart I(exact numbers can be argued, range is right). That puts almost nothing near the stop/station so there won't be a transit in there.

Reston has public transport. Most of Florida doesn't. A shiny nickel says that the pictured development has a nod to public transport in the form of a shuttle van that loops around the parking lots and the main street once every hour or so.
