The disclosure includes embodiments for providing a service to a vehicle via a macro-vehicular cloud. A method, according to some embodiments, is implemented by the vehicle which communicatively coupled to the macro-vehicular cloud via a non-infrastructure network. The macro-vehicular cloud includes a plurality of micro-vehicular clouds which each include a set of onboard vehicle computers that are operable to provide a set of computing resources to the macro-vehicular cloud via the non-infrastructure network. The method includes transmitting, via the non-infrastructure network, a wireless message requesting a merge service from the macro-vehicular cloud. The method includes receiving, via the non-infrastructure network, the merge service from the set of computing resources of the macro-vehicular cloud. The merge service includes the macro-vehicular cloud instructing the vehicle to merge into a lane of a roadway.
