Bingo. I support 100% the fact that as professionals we have the responsibility on our end to make sure we maximize our rest; that being said when the company schedules an 8 hr overnight with a 45 min. van ride, you end up with 4 to 5 hours of sleep.

All studies point to two key figures:

1) 16 hours time since awake - which means that by all measured studies after 16 hours of being awake most subject's performance was significantly degraded.

2) The average subject needs 5 hours of sleep minimum to function, anything under 5 hours becomes sleep deprivation and also degrades performance.

Make of it what you will, but the fatigue factor has to be addressed from all angles, not just the pilots.
