A problem with the new Endurance Races is that if you are two or three minutes behind the leader, the race will end before you get to the finish line to ‘complete’ the race, and you will receive a DNF.
There’s a few options to go about this.
Increase the timer to three or four minutes to allow all racers to complete the final lap of Le Mans or Nurburgring
Or, Remove the timer entirely
Or, allow the race leader and all finishers to leave before everyone else so they aren’t stuck waiting for the ones who were lagging behind so they don’t get a DNF.
