We will never be ready to transmit the given message in (disconnect or invalid request).

Frees resources associated with car. We don't explicitly tell the client, it'll learn with the disconnect (or violated the protocol).

Parameters
carrequest that now permanently failed; the responsibility for the handle is now returned to CLIENTS (SESSIONS is done with it).
