It would be operational by now and would have connected all the major urban areas in the region. 45 min trip instead of a 5 hour drive.
I will never not be salty about that. Because all we got instead are busses that take 4x as long as driving -and- cost a lot.
I read an article about that and apparently the change to the model made the ai stop responding to affectionate solicitations with the same sort of affectionate tone in reply. It got more businesslike, and less intimate.
