I recently talked with someone who has insight into FDOT thinking. Rail transit is off at least 25 years due to not enough trips projected anytime soon in NE Florida, even accounting for current growth trends. Our best chance is Brightline.
For now, we need a very robust and well managed bus system. Quick to implement, flexible to adjust, and relatively cheap compared to other transit possibilities other than, maybe, a trolley system in the inner core if Downtown could ever get its act together and create substantial density.
Honestly, between JTA and our historical approach to mass transit, I expect more of the garbage system we have today for the balance of my years on Earth.
