For example, will people be willing to commute longer distances? Will smaller cities outside larger metropolitan areas become more popular?
Automation to that degree would likely have wiped out many other non-driving jobs in the city, or made them such that doing the job remotely was possible.
There's a huge difference between meeting online and meeting offline. Online might become a venerable substitute for offline if VR/AR technology advances to the point where we can have the full experience of the other people sitting around the same table, i.e. their whole body language etc.
This is all things equal, and assuming that the advent of self-driving cars doesn't also bring a whole new economy/job market.
I think this is fairly unlikely to stay a permanent source of inequality between classes of people. I also think it is very likely that people who don't notice the wage reactions will continue to complain about it indefinitely, though.
I'd be happy to pay triple my current commute expense in return for two things:
1) A vehicle that picks me up on-demand from my home and which goes exactly where I'm headed, so I don't have to commute to and from BART.
2) A vehicle populated only by other paying customers, with a mechanism to eject bad actors from the system.
That would have a huge effect.
90 mile circle around London covers the entire south east of the UK pretty much.
90 miles from Leeds covers Manchester, Liverpool, Birmingham,bradford and Hull which is much of all the major cities outside of London in the midlands/north.
I would probably prefer my Dönercopter delivery.
As self-driving cars are introduced, places that previously had terrible public transport access, yet are still within a 45 min drive of CBDs via driving will have mini-booms.
