Brightline is partnering with a limo-type company at MCO, rather than uber/lyft. I can't think of an airline that's done that.

On opening day of WPB - MCO, one commenter on youtube said there was a noticeably flat wheel. BL does need to emergency stop fairly often. Also noted was that BL has to negotiate with FECR, not always cordially. The proposed partnership with Sunrail also came up as contentious. These are all normal railroad things.
The persistent argument that people need their cars at their destination came up a lot, with the retort that flying is the same.
Miles in Transit mentioned several times he thought that having security screening was odd. Welcome to Florida, land of gated communities and HOA's. Tri-Rail was the direct competition on MIA-WPB, going through an area of less wealth, and wealth disparity, than BL's coastal route. Then again, this is the guy who reviewed the North Philadelphia Amtrak station, a sort of disaster zone. (One with potential, since the North Broad Street commuter station is nearby, he noted.)
Also, many people don't know new BL stations are paid for by local governments.
