Nothing in this convinces me this is better than trams.
Why not use rails for this?
Remember, we need the ability to have inexpensive entries and exits from the system. This is both so we can provide easy emergency exits, so we can reduce the amount of surface road required for the last-mile trips, and so we can spend less land for the entire project. Rails have low friction which makes significant slopes impossible; without significant slopes, we cannot have cheap connections between underground and surface; without those cheap connections, the entire system economically falls apart.
In addition, part of how the system works is that self-driving cars can travel along residential roads to bring you straight to your destination. Rails would require that we build rails into every road in residential areas. This is just not economically feasible.
Don't need exits if you build those trams on the roads. Which suddenly makes the whole cost factor disappear either, and the "people are getting burned alive in tunnels" thing. And the "needs cars" thing.
Imagine obsessing this fucking much about skin colour.
