How do autonomous vehicles communicate with each other and infrastructure?

Instruction: Explain the technologies and protocols involved in vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication.

Context: This question delves into the candidate's understanding of V2V and V2I communication systems, crucial for coordinated and safe autonomous vehicle operations.

Example Answer

V2V exchanges information between nearby vehicles, but I would specify the radio technology, message standard and jurisdiction. DSRC is important historically; the FCC adopted rules transitioning US 5.9 GHz ITS operation to C-V2X. That does not describe every country or installed system. A message format and a transport are separate choices, and message frequency depends on the application and congestion controls. I would treat received reports as time-sensitive supplementary evidence, not a substitute for local perception.

Make it your own

Illustrative interoperability checklist: regional spectrum rules, radio profile, message schema, timestamps, credentials, update rate and behavior when peers are absent.

Why this works

The US-specific correction avoids replacing one universal claim with another. Follow-up: can two vehicles understand the same message schema while using incompatible radios?
