IMO, the only way this will work is if the network is autonomous, not the individual vehicle, and every vehicle will have to be connected to the network, no exceptions. I'm reminded of this as a Chandler, AZ resident where Waymo cars travel on nice straight, flat grids, with lane lines and easy line of sight with everything, versus what I observe spending time in New Jersey occasionally (no Waymo cars) where there are roundabouts, stop signs with obstructed views of the adjacent roads, hills, and everything else you can name that will overwhelm a vehicle's decision making capabilities. Then throw inclement weather for a good part of the year on top of it. If we as individuals want to share driving autonomy with the tech I don't believe it will work. We constantly break road rules that will ensure conflict on the road with self-driving vehicles.

What is an autonomous network? How does it recognize obstacles? How is latency and loss of signal handled?

1) That's called train. 2) Not gonna happen for normal roads, because it is worthless waste of resources and yet there is lot of additional variables, which you can't control, like people or animals entering the road.

That doesn't work unless you also eliminate all cars under direct human control, which is not practical, possible, or desirable. And BTW, forcing adoption of automated cars only will quickly lead to situations like the one where you can lay down a chalk line around an automated car, and it winds up being immobilized to avoid crossing the lines. Far worse sabotage will ensue...

During my university years I used to bore everyone I could with this idea. I became quite obsessed with it and spent a lot of time working on simulations, the basic idea being that if we modelled a road network as a DAG, with intersections as vertices and "segments" (sections of a road between any two intersections) as edges, then the network itself could route traffic, allowing for balancing of load, priority of emergency vehicles, etc. An individual segment would be responsible for the transit of each of the vehicles on it, and each intersection would be responsible for transiting each vehicle through. The vehicles themselves would just be told what to do. One of the main benefits I was interested in was the notion that an efficient network would likely mean that the speed of the vehicles could be brought right down to something pedestrian friendly. Over the last few years I've watched with horror the version of autonomous vehicles that we seem to be getting, and I keep telling myself I'll dust off my old prototype and share it, but then paying the rent gets in the way (as an aside, the code has proven to be of some use - it forms the core of jsPlumb's Toolkit edition). I must admit to being increasingly skeptical of my original idea, though. As someone else mentioned, defining the interface between pedestrians and one of these autonomous vehicles is tricky. The easiest thing to do would be to completely ban pedestrians from the space used by the vehicles, which would be awful.

    Yes, exactly. The story of how that came to pass is really infuriating.
