At least in the bay area, the main feature is that this is an illegal bus.

Each city council is able to sabotage bus services through their area, and they do. It inflates property values and keeps “undesirable” people out.

This bypasses the intentional sabotage that’s been applied to bay area public transit. Of course, it’ll still be much, much worse than a competent bus system. I wonder how well it will work in other countries.
