I'm not a bus rider but I remember a JTA article around here and some other comments mentioning how bad they were.
Won't using Streetcars force JTA to be more competent too? A streetcar is forced on a certain route due to it's tracks. JTA says it's bad but isn't that a good thing? That means that route will never change and due to the high price of a streetcar, it will probably be tracked by some type of central command. Since it is a brand new streetcar system, each one could also be easily added to a website to track the location of each car via my smartphone.
Of course, I'm probably just dreaming right now. There's a right way to build a streetcar system and there's a wrong way. I'm a bit worried that if Jax does approve this, it will be a "streetcar to nowhere." In a way, lots of lobbying would be needed on the stops this thing would take and thus killing the project because people would say "see, we built this line here and nobody would ride it!"
