You've never had a bad night's sleep? Never had to make a longish unexpected trip because of a family emergency? Never had to work 2 jobs to make ends meet?

In this case, if the person isn't able to get disability b/c of their condition, I can't fault them for doing what they need to survive. I don't like that it puts others at risk, and hope they are taking steps to reduce the risk. Detection technology that alerts them seems like a step in the right direction.

I've had to do all of those things. At some times in my life, I've had the first and last for an extended period. To my knowledge, I have never as a result driven in a condition that made me unsafe behind the wheel, though.

Yours is another comment that talks about people doing what they need to do to survive, which is an ironic characterisation given we're talking about behaviour that is borderline suicidal.

If you have done those things, then you've accepted some increased risk of falling asleep, just like most of us have at one time or another. We're human and can't say for certain that falling asleep is impossible (or some other medical event won't happen).

We live with that risk, and some others have to live with more risk because of their circumstances. I'm more reacting to all the posts that no one should ever drive at all with even the slightest risk that they'll fall asleep, which is just an unrealistic ideal for most of us.

You know they let some people drive who have extremely bad eyesight--bad enough that that they can't read road signs? Yet they are allowed to drive, because not driving makes participation in our economy next to impossible.

Comments like this are side-tracking the discussion. The original premise wasn't that sometimes everyone is a bit more alert or tired than others. It was someone who knew very well that they had a history of falling asleep at the wheel and wanted to continue driving apparently knowing it was likely to happen again.

Of course not. But normal people with a healthy lifestyle don't just randomly fall asleep at the wheel in the absence of a serious (but perhaps undiagnosed) medical condition. The way a lot of the comments in this thread are defending driving while tired, you'd think millions of people could all just doze off without any warning or awareness that they were at unusually high risk.

In my country, such poor vision would (if not properly corrected) immediately disqualify you from holding a driving licence. This is a policy that I entirely agree with, so we apparently come from very different perspectives here.

Then you pay for a taxi, bus, or some other mode of transportation unless you're prepared to pay both financially and emotionally for any incident you wind up causing. Both for yourself and everyone else affected.

It's really not that complicated. Stop making choices for other people that could cause them to wind up injured or killed. Because yes, that is in fact what you're saying to do here.
