Yeah, it becomes a brainer, though, when you ask “how do you deal with malicious transmitters”, since the answer to that tends to involve developing the systems to monitor the same variables externally without trusting the transmitted values, and once you do that, what is he transmitted data for?

Using transmitted data for less safety-critical things like route intent for efficient holisitc route optimization, with a penalty system for misrepresentation might be useful, though.
