You still have legal 561 hours left, but you are fighting sleep on an evening autocar with belted passengers. What should you do?

1. Increase speed to 100 km/h so you reach the hotel before micro-sleeps start
2. Open the rear emergency exits for cold air and continue
3. Let a passenger without a D licence take over while you nap in the front seats
4. Stop in a safe place, protect the passengers, and rest; remaining legal hours do not make an unfit driver safe
