Why does Goal 3.4 call the work/rest cycle 'basic' for a professional driver?

1. Because rest is optional if ESP is on
2. Because fatigue and stress have causes and effects that the 561/2006 rest structure is meant to limit, and diet, alcohol and drugs can destroy that limit
3. Because weekly rest is only 7 hours like a periodic-training block
4. Because open questions in part 1 are unmarked if you are tired
