It’s not as good as trains running on electrified rails because steel wheels are inherently more durable, but as long as you’re going to have a system of roads, these are not too bad of a choice.
This will be an issue if this is not just used as an intermediate solution until real tracks are build. This thing seems to have all wheel steering and therefore all wheels will roll along exactly the same path on the road and increase the creation of ruts. But as long as the road is properly maintained it seems to be way better then a normal bus. Not only capacity wise but especially comfort wise, given that longer and larger vehicles usually imply a smoother ride compared to "short" busses (even though the word short seems to be a bit off for something that is usually 12 to 20m long).
Weird thing is it's only called that way if you switch it to english. Was looking at the italian menu and couldn't figure it out since there were also weird names on but the one you mentioned is just called rib eye so I immediately scrolled over it.
So most probably at least nearly nobody is going to order it with that name, can't imagine them having a lot of english menues available outside the airport locations and the ones in the centres of big, touristy cities.
