I see self driving cars as a backwards compatible way for us to reimagine infrastructure.
Right now, SDC is operating in the real world, in non-trivial environments (San Francisco), without special road infrastructure to make them work. It’s beautifully backwards compatible, at the cost of not being generalized (the service areas are extensively mapped).
Once SDC take off we’ll likely start getting infrastructure and rules to support them. Think standards for communicating position locally - ie car A broadcasts its position and route to cars B, C, D within 200m, special road infrastructure to make lanes and corners more manageable for SDC, rules against aimless circling. There’s already a carrying cost in the form of gas or electricity plus wear incentivizing aimless driving, also the opportunity cost of not actively moving someone or something, but we can probably introduce some kind of toll or tax on a SDC operating with no humans inside it to further disincentivize this.
A very useful thing about SDC, and something I think people forget about rideshare and taxis, is that they let people move around independently without needing parking for those trips. In dense cities like SF and NYC that’s hugely useful. A single rideshare or SDC can move 10 people on custom routes without any of those people needing to find and pay for parking, and without using any parking infrastructure. That’s great because it disincentivizes wasting more space on parking in aggregate. Over time this should let us build denser.
Of course, public transit could obviate all these concerns, and I’m a big believer in funding way more public transit than we do already, but it will take a lot of time and political will to make that happen in the US. And it still does not offer the flexibility of SDC and rideshare. SDC is fully compatible with existing infrastructure and may give us a way to morph into public transit more smoothly with things like dynamically routed SDBusses and a reduction of parking infrastructure leading to denser urban environments that more easily support public transit. I think we can solve the “spending too much time on the road doing nothing” problem with congestion pricing, which we should really be doing already.
That picture has the cars bumper to bumper, which is likely rather better than even the self-driving best case. Cars take up a lot of space.
I can imagine interesting and efficient ways to move large numbers of people that involve self-driving vehicles for part of the journey, but for high capacity at reasonable cost and space utilization, feet, bicycles, busses, trains, subways, etc are dramatically better.
I believe the feedback loop is that so many leave due to bad living conditions (mainly driven by cost and commutes) that there are plenty of jobs to get which makes people want to move there.

GP's implication was that SF has abundant jobs because so many people leave and I was clarifying how that is a misconception.
Your point is different entirely, but thank you for making it.
The most enjoyable cities/suburbs I've experienced around the world have been fairly dense in terms of narrow streets and multi storey buildings. 3-6 storey buildings on average. NYC and SF already have a good amount like this, though still dominated by roads. There'd also be scope to turn parking lots into actual parks or multi-purpose areas for events, food stalls and so on. Parking lots are just grim.
