Actually the weight savings is irrelevant. The advantage is in the simplification of the cable assemblies! Did you know that just about every cable assembly in every car is made by hand‽ Hackaday wrote an article all about it: https://hackaday.com/2022/07/27/the-surprisingly-manual-process-of-building-automotive-wire-harnesses/ https://hackaday.com/2022/07/27/the-surprisingly-manual-proc... By having just one wire to transmit data and power to components in each zone it will be a significant cost savings. It also makes the various automotive engineer's jobs a lot easier.

So that makes me a bit concerned. This a single conduit with collision detection. All fine and good. So does that mean every PCB and subassembly/controller in a car will be daisy-chained? Would one single broken wire disable the entire car or just the downstream modules? Do you create a "backbone" down the length of the car and fan the signal out like a nervous system?

  It won't be that everything in the car is connected on one bus. What is more likely is that you have a zonal ECU that controls a group of a few sensors and actuators. That zonal ECU will likely be connected to other parts of the vehicle through more traditional Ethernet. The 10BASE-T1S standard requires that it can support a minimum of 8 nodes on the bus although you can support more but you aren't going to be hooking up absolutely everything together on it. >Would one single broken wire disable the entire car Not in this case but try shorting the two CAN bus wires together in an older vehicle.
