Ok, I wanted to check weather I missed something so I went back in game and made sure 'Fatigue Simulation' was checked then did a run from Reno to Bakersfield and my Fatigue number stayed at 14hrs. Which is why I said the fatigue system was disabled.
No its not realistic to nap for 10hrs and wake up at the same time you went to sleep, almost as unrealistic as driving Las Angles to Jackpot and back in 1 sitting without dying. I'm suggesting a way to simulate the need for rest without messing with time of the game. And the time of the game can not be messed with we all have to be synchronized for online play.
