They don’t have the boring normal stuff you need for an actual transit line, like service access or evacuation routes or proper ventilation. They’re being disruptive by ignoring everything we’ve learned since the 1800s about tunnel building. It might be easier to retrofit than dig a fresh tunnel, but at that point you’re limited to the route they dug, which probably isn’t as useful for transporting people instead of cars.
The routes themselves are bad. The tunnels run below already existing state highways. It saves them admin time only having to get approval from the agency that manages the highways, but makes it a poor choice for a transit line.
A conversion could be useful for getting people to the city center from the airport. But any station along the route would be difficult to access, unpleasant to be in, and be of little use to anyone being buried under a highway.
