Disclosed herein is a method and system for minimizing the required bandwidth for a cloud based unicast communication with a vehicle operating within a road network, where the cloud comprises a cloud logic and the vehicle comprises a vehicle internal logic. The method comprising the steps of: determining a current position with direction of the vehicle within the road network; setting an interval at which the vehicle is to report an update on its position based on a most probable path of the vehicle and the complexity thereof, where the most probable path is a set of possible paths a predetermined distance ahead of the vehicle that it is most probable to travel along given its current position with direction within the road network; communicating the set interval to the vehicle internal logic; and reporting an updated current position of the vehicle to the cloud with the set reporting interval.
