To me a big part of this problem is the dependence states and local communities have on the federal government for funding. There was no option from the federal government to build a new Tampa-Orlando rail corridor that was high speed ready but would use cheaper conventional trains for the mean time.
The one park of the equation that is almost totally ignored is actively making driving miserable. Transit being available is not enough. Every city with a great transit system is still clogged with cars.
Gas prices have proven to be far more inelastic than ever expected. Back when the Tampa-Orlando high speed rail project was still alive a lot of math was being done here discussing its ineffectiveness. I believe it came out that for a family of four looking to go the whole route gas would have to pass $10/gallon before the high speed train become a cost effective choice.
All very, very valid points. But no reason for the state to not consider rail to alleviate what is quickly becoming gridlock in South Florida. I'm sure the most frequent posters on this thread, like me, live in Florida. How many more times can I-75 (I've not driven I-95 since the mid to late 1990s, so I cannot comment with accuracy on its current state) be widen? It seems to be in a constant state of repair due to the high volume of traffic. Florida does have a good freight rail system, so why not a comparable passenger one? It takes years to plan and construct major transportation like this (please Florida, DO NOT take the model of Amtrak and use the existing freight rail lines), so by the time the Legislature gets around to doing something, I probably will be so old I will be living in a nursing home and won't care or dead. Which is why I want that All Florida Train to succeed so we will see more.
