The method also includes determining, for each destination, at least one route to the destination, resulting in a plurality of routes at least one of which corresponds to each destination, including determining a statistical likelihood of the vehicle remaining on an intersection-exit that is along a potential route and selecting at least one route to each destination with the highest statistical likelihood. Responsive to the vehicle no longer being on a selected route, selecting at least one new route to the at least one destination.
