Example Answer

I would use a blockchain only where a shared ledger solves a concrete multi-party trust problem. It can record service transactions or software provenance, but recording a V2X report does not prove it is accurate. For charging payments, a contract still needs trustworthy evidence of the charging session; that is an off-chain input or oracle problem. Time-critical driving messages should not depend on ledger consensus. I would compare complexity, privacy and recovery with a conventional signed transaction service.

Make it your own

Illustrative payment case: two reports disagree about delivered energy. Define the authenticated meter, dispute process and idempotent payment identifier before choosing the ledger.

Why this works

Consensus protects a record under assumptions; it does not validate a physical event. Follow-up: who can correct an erroneous bill without erasing the audit trail?
