I can't answer the question of why does Jax and JTA have to go this route but that's the goal. Unfortunately, like all of us here already know, the technology isn't there yet and there's no promise that it will ever be anytime soon. For me, there was not much to say, as this has become a plan to run a few AV cars in mixed traffic with human attendants. Like Lake Nona, Gainesville and other communities, doing that can be done. Until the technology advances and vehicles become larger and faster, it will seem more experimental than anything else.
