Personally I have never found the zombie discussion helpful, and here I think it is confusing.
We do have the ability to respond to stimuli without being consciousness. If someone's foot is pricked with a pin when they are asleep, they will move the foot. We don't need to introduce anything as exotic as "zombies" to understand this.
We don't need to introduce "zombism" to understand what happens with long distance driving and sport: some actions which initially required full attention can gradually require less and less. But unless the driver falls asleep then he is still seeing the road and the other vehicles, still experiencing something, and this is just the way things normally work, it isn't "partial zombiness".
Dretske says the same thing when he claims that the long distance truck driver is always, to some extent conscious. He is not a zombie lacking all experience. Dretske says that the only sense in which the driver's mental state is unconscious(not having experience), is when the driver is not conscious of having those states.
The way you have phrased this isn't entirely clear, but I think I agree with Dretske.
It seems we can never claim a zombie in the full sense of the word ( person lacking all experience), because we are always conscious of our environment, so we always experience something. Even if it is only to a limited experience. This seems to be true if we consider attention in relation to consciousness. It is impossible to catch ourselves not attending to something. We are doomed to always experience the world in some way. This is basically why Chalmers rejects the possibility of actual zombies. Keeping in mind he is talking about a being that lacks all experience.
I don't follow your explanation here. When we are asleep we don't experience the world but we can respond to stimuli.
It is claimed by people such as Armstrong that the mental functioning of the driver could be considered the, 'not conscious' aspect of the driving process. Another way of saying this is that functional role of attention is the non-experiential aspect of driving on automatic pilot. As we have seen Dretske rejects Armstrong on the basis of the driver not being conscious. The accepted explanation is that the driver on his journey has many and varied experiences it just that he is not attending to the majority of these experiences and this is why he cannot recall the details of his trip. One important assumption here is that at the very least the driver was attending to something from time to time.
"Attending to something" is a different level of consciousness, even when he isn't attending to something he is still seeing the road, otherwise he would crash. I don't think it is "attention" that determines whether he can recall the details of the trip, I think it is a question of whether the experience was committed to memory or not.
The other assumption that goes along with this that it is impossible for any human to be in a completely functional state.
I don't understand what you mean by this. If I'm asleep and not dreaming and you p**** my foot and I move it, am I in a "completely functional state"? Perhaps it would be better to say a "purely functional state"; or perhaps it would be better not to use the concept "function/functional".
We need to experience something in order to function and of course, we can never catch ourselves in a state of non-attention.
No, but that doesn't mean we can't be in one.
I think the assumption that one must necessarily experience their environment is actually wrong.
One only experiences the environment when one is conscious. That's more or less the definition of consciousness. If someone isn't experiencing the environment they are unconscious.
You seem to be claiming you can be conscious without experiencing. Since you say they are synonyms, that doesn't seem possible.
