A fuel dispenser comprises fuel flow piping defining a flow path from a source of fuel toward a fueling nozzle. A plurality of fuel handling components are disposed along the fuel flow piping. Control electronics are in operative communication with the fluid handling components. The fuel dispenser further includes network circuitry operative to create an ad hoc wireless network with an adjacent vehicle and, after creation of such network, exchange security indicia with the vehicle that identifies the fuel dispenser as a trusted road side unit. Thereafter, the fuel dispenser facilitates a communication link with a remote server for bulk data transfer to the vehicle of information unrelated to a fueling transaction.
