Just a thought, I can't sleep on command. If I'm tired I can sleep, if I'm not I can't. It's that simple. I cannot put my head down during the day to ensure that I'm properly rested for the evening unless I'm already tired. Just one of those things I'm afraid.
I sincerely hope that I always make it home - I have practically fallen asleep at the wheel before on a couple of occasions after a duty. It is not a pleasant experience and I have been extremely lucky.
Some people may consider me foolhardy for putting myself in that situation. As someone has already said, it's illegal to stop on the hard shoulder unless it's an emergency so my options were a little limited. (Not driving was not a viable alternative).
Something must be done, ie. HOTAC or a driver, to alleviate this situation. Otherwise, let's hope that BALPAs legal protection is worth my 1%.
