As Donald mentioned, Ethertypes (also capitalized EtherTypes) are administered by the IEEE Registration Authority ( <>).  The referenced web page also includes a link to the Ethertype public listing.  An applicant cannot request a specific Ethertype number.  There is no experimental Ethertype expressly assigned for vehicular protocols.

IEEE Std 802 defines Experimental Ethertypes, and those can be used for protocol development, but an assignment is required for general use once the protocol is ready for deployment.  The Experimental Ethertype also includes specification of the sub typing that is now preferred in protocols.  (If sub typing is not used as explained in IEEE Std 802, an equivalent mechanism with explanation will be required to receive an assignment, as will an explanation of why subtypes of an existing assignment can’t be used for the protocol.)

Donald Eastlake (primary) and Juan Carlos Zuniga (secondary) are the IANA-designated experts for Ethertypes.
