Question about Sleeping

[rocky1987]

Can we decide how much time we want to sleep? Because sometimes we need to sleep like an hour more so we won't be late.
For example i had 6H to finish the delivery and had 5.30H to sleep before i get tired, and there was 8H that i needed to deliver the cargo before it, so if i slept it will be for 5:30H to reach 11H and i'll be late

increase you speed, sit at 110kmph for 2-3 hours, the time will come down, you'll have extra 1 hour for delivery.
