Oh, that's back? I thought that died with the "V2V" scheme, which was used as a justification for 5G cellular. The document [1] comes across as a solution looking for a problem. Like much of IoT.
Waymo cars do not have, or need, a vehicle to vehicle communication system. They talk to their HQ, but that's not part of the main control loops. Most of the problems Waymos have to avoid don't communicate much, if at all. Traffic cones, pedestrians, bicyclists, and people in wheelchairs have to be sensed directly. Once you have the sensing to do that, large vehicles should not be a problem. (Yes, Tesla has had trouble sensing fire trucks, semis, etc., but that's a Tesla problem)
It doesn't seem to be necessary that traffic lights and signs broadcast their status to vehicles. It's not something Waymo has asked for.
So what is this "V2X" thing supposed to be for? Surveillance, probably.
