People make mistakes. Like texting, picking up things they dropped, seeing-without-noticing, or falling asleep. That's generally why and how the really bad accidents happen. And in most of these cases, it's a really good idea NOT being in the lane.
Take the shoulder, if it's of any use at all.
Edit: And there's one more reason for not taking the lane on high speed, heavy traffic roads: People tend to tailgate, and if one driver sees you a little late, and swerves to avoid hitting you, the one behind him may not be able to react in time.
