The YouTuber Not Just Bikes recently put out a video arguing that self driving cars will allow for and encourage policy and urban design that is even worse than current car-centric cities. Maybe too sensationalist, but they are interesting points to consider. https://www.youtube.com/watch?v=040ejWnFkj0
It does seem clear to me that the solution to "self driving cars that rely on an interconnected communication network to maximize driving efficiency sometimes run into jaywalkers and bikers" is banning jaywalkers and bikers for many car first people. Probably will lead to even more cultural divide between sun belt and non sun belt dwellers. Even my city of chicago which is easily top 5 best city for non car transportation in the US is very pro car politically. I could easily see the city government going for the ban all non cars from streets route
