The article doesn't make it clear to me when the DOT talks about "V2X being deployed", what the full scope of that is – does it refer to just the physical technologies, or the lowest layers of the OSI model? Or does "V2X deployment" here mean more application-level stuff, i.e. a series of minimum requirements about what information classes of devices will broadcast to other classes of devices, with what limitations? Without that clarification, I think the first thing readers of HN will think, justifiably, is "is all of my car's information being broadcast all the time to everything", for plenty of reasons – dragnet surveillance, disruptive attacks ranging from Flipper pranks to state actors, etc.? It's not clear whether that's true or expected of this V2X initiative. After some quick digging, it looks like so far, it looks like only very domain-specific features have been "implemented with V2X", and will be for the forseeable future (see p7+ in [1]) – oversize vehicle complaince, pedestrian in crosswalk, blind spot warnings. How that's implemented will probably need a lot more digging. [1] https://rosap.ntl.bts.gov/view/dot/68128 https://rosap.ntl.bts.gov/view/dot/68128
