IMO your statement is the truism that isn't adding anything. Obviously people that might fall asleep shouldn't drive. But this is a matter of degree. Everyone might fall asleep and it's a risk everyone will eventually take even in a small degree. Some people are always somewhat tired (eg sleep apnea or CFS), some people aren't tired when they start driving but become impaired at some point. Some people might have an undiagnosed condition that contributes. There's no reason to not celebrate a simple advancement that might save people from a disaster.

>But this is a matter of degree. This is it. I don't understand why this isn't higher up in the discussion. Do you check whether your brakes work every time before setting off? Do you check whether your wheels are attached properly every time before setting off? There are a million things that could break on your car. They're just very unlikely to happen. Pilots/maintenance crew for planes checks that kind of stuff for virtually every flight. We accept this small risk with cars. In return we get an enormous increase in efficiency. If everyone had to do a 5 minute check on their car every time before setting off, then that would be a lot of productive time spent on it.
