Level 3 autonomous driving isn't made with the use case of sleeping but with you being able to do other things while still awake (for example use your phone or watch a movie). For those situations 10s is more than enough time to react.

If you're not paying attention, you can easily end up dozing off. You're either more or less paying attention--and yes drivers' attentions can drift a bit--or you're going to take some time to reacquire some awareness of what exactly is going on.

If you can't stay awake then you need to not use this feature. If you're not exhausted it should be an easy task. If you are exhausted, arrange something else.

Attention drifting is supposed to be fine. That's the entire point of level 3. How long do you think you need to regain focus? Maybe a different brand will cater to that amount of time, or you can lobby regulators.

My point was simply that, if you're not driving and are absorbed in something else whether a book, a movie, a game, or just zoned out, 10 seconds is not a lot of time to figure out what's going on because the car's computer has encountered something that is sufficiently non-standard that it doesn't know what to do.

I do there there is some period of time that is reasonable for a handoff. Maybe a minute? I actually believe that full autonomous driving with geo-gating and condition-restricted limits is probably how things will play out.

We’ve gone from “unless you’re actively engaged you can’t possibly be ready to takeover immediately” to “unless you’re actively engaged you are easily going to be sleeping”.

People fall asleep behind the wheel all the time. They just usually crash and maybe die when this happens, if FSD is not enabled at the time.
