And still to add BE58 and Parker among others are correct. The flight following is a privalege offered buy towers and FSS vor VFR flights based soley on controller availability.  Wich here in FS is not the case.  The thing in the sim that do hold true are of course being handed off to different centers and controllers.  But this again is dependant on the centers workload.  Don't know if the game highlights that But you could fly the same route VFR and fly then  IFR and in the real world you would almost definately be handed off to different flight centers. IFR taking priority.  I figure this would either help relate or just  re state what others say. but every little bit helps.
