Companies like this team up with the government to steamroll, figuratively and literally (IIRC, this thing has killed 3 people already), small towns for the benefit of nasty cities like Miami.
I really feel like this attitude really hurts the US in catching up with the rest of the world in good, affordable public transportation (which we are decades behind in). Australia has fewer people and is less densely populated than the US and most of their capital cities have really good train+bus systems.
I think to that Ben Sollee song, "In America, in America, they bury us, with our cars."
But hey, as long as we can provide an affordable way for transients to get to and from the needle exchange safely.
From my experience, a majority of the members here believe in collectivism / socialism and not in individual rights, and are big city dwellers that thing small towns and their constituents are a disease.
My parents, who still live in Florida, regularly give me an earful about the train. To an extent, I can see where they're coming from: there has been some controversy over who will pay for crossing upgrades to handle these faster trains, and increased train traffic will mean increased crossing delays in these smaller towns. There have also been some well-publicized pedestrian deaths (https://bit.ly/2GA0QN2) along Brightline's existing route.
But I'm in favor of these trains, and I think most of the opposition amounts to classic NIMBYism. Transportation in Florida is a nightmare, and passenger rail is the obvious solution. And I find it inconceivable that any accidental deaths due to the additional train traffic won't be offset by even fewer deaths on the highways.
Florida has a proud history of rail transportation (there's a reason Florida has an entire county named after Henry Flagler), and Brightline could be a return to some of those past glories: https://en.wikipedia.org/wiki/Overseas_Railroad
