The disclosure includes embodiments for a vehicle to select one of a plurality of different interface types to use for a first time period. A method according to some embodiments includes analyzing probability data describing a set of expected channel loads for the plurality of different interface types to make an initial interface decision to designate a first interface type from the plurality as an interface type to use for sending and receiving wireless messages during the first time period. The method includes determining that the initial interface decision is invalid by analyzing load data describing a set of measured channel loads for the plurality. The method includes analyzing the load data to make an overriding interface decision to designate a second interface type from the plurality as the interface type to use for sending and receiving wireless messages during the first time period.
