It's one thing having the technology in place - and we're some way away from having something that can manage London - it's another thing entirely getting it deployed.
Driverless trains have been a technical reality for decades; the Tube still has drivers (and "captains").
We're heading into a strange political and social realm not too unlike the beginnings of Soviet Russia, except this time the causal factors aren't transient; technology is here to stay.
It seems to me like the 1% is going to keep growing and growing until it pops under the weight of its own automation. From there it seems likely governments will assimilate company's resources and distribute them more-or-less equally. Its not something to worry about for a few decades, but automation is speeding up. Many of us will grow to old age in a very different world.
The thing that will hold up real deployment of this will be unions rather than the technology.
