He drives on one of these endless, lonely roads and overtakes a huge monster of trucks, everything is as usual. The truck catches up again and Mr. Mann is angry, the usual overtaking skirmish begins. But the monster cannot be shaken off and neither can the tension of the spectators, it does not let go of him for a moment.
