After arriving the end of the final route the vehicle will be removed from the net.
-> The error can also emerge when moving around stopped vehicles but this might not be your use case here. * @DLR-Team: maybe it would be an enhancement to get the sumo warnings via traci as well. > Are they both caused by the same reason?
