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).
