A first message is broadcasted to a plurality of remote computers identifying an attribute of a host vehicle. A second message including a request to receive data about the identified attribute in response to broadcasting the first message is received from one of the remote computers. Upon receiving the second message, a host vehicle component is actuated to output at least one of light or sound associated with the identified attribute.
