Here's a guy reviewing their Miami to Orlando service.
I feel like this one is actually a better financial bet than the Florida one. Much faster relative to flying or driving, given that it doesn't have to slow down through cities, and there's a huge amount of back and forth traffic to capture. Unlike the State of California, this company has already shown they know how to build and operate a system. It also has significant support not just from California, but also the state of Nevada.
