IF the other observers exist as you believe you exist that is...
You doubt it?
Who are you writing to if you are not certain anyone is conscious of and reading what you write? What do you think certainty is?
I (philosophically) doubt everything...
Beyond the fact that statement is a logical contradiction in the same way, "nothing I say is true," is a logical contradiction {if you doubt everything then you doubt you doubt everything], it is not possible to begin with doubt. Before can doubt anything you must have something in mind to doubt, something that you identify as something, only after which can it be questioned or doubted.

... it could be as it appears, it could be brains in vats or evil demons, elaborate dreams/hallucinations...
Not unless there are vats, demons, dreams, or hallucinations, which really are doubtful.

... one acts habitually- without deep thought in the instant...
Habituated behavior still must be chosen. One cannot form habits without first consciously, "practicing," behavior which beomes, "automated," and one can always choose not to do what one's habituated behavior prompts. While everything is going well, one does not have to pay attention to their driving, but the moment something unusual happens (like the care stopping suddenly in front of you) deliberate conscious behavior takes over.
No one knows what actually occurs in another individual's consciousness, but from all I do know about those who claim extreme scepticism, there is a common motive which is, like all other repudiations of knowledge, an attempt to evade one's responsibility for their own choices and actions. After all, if they can't know what is true, or correct, or right, how can they be responsible for their choices. It's also why volition itself is denied, as though one denying they actually consciously and deliberately choose what they do lets them off the hook. Of course it doesn't. Reality never forgives.
I wrote a couple of article about skepticism and cynicism about six years ago. Since most people around here don't like links the following is excerpted from one of those articles:
Skepticism About Objective Knowledge Actually Gullibility
Human beings are not born skeptical. You might say human beings are born gullible. Most children believe everything they are taught, and since they are usually taught by people who love them and would not intentionally deceive them, there is nothing wrong with that gullibility. It will not be long in most children's experience before some expectation or belief is disappointed or dramatically falsified. The nice looking buzzing fuzzy creature stings.
One learns to be skeptical, skeptical of first impressions, of what one is taught, and of what others say, at first from experience. That learned skepticism is itself a kind of knowledge, knowledge that something is only true if one knows why it is true. True skepticism is built on one's conviction they can know the difference between truth and falsehood, and that it is always the truth that is the cure for credulity and superstition. One knows what is false because one knows what is true, and a thing is false because it contradicts the truth.
What is wrong with radical skepticism is that it denies one can know the truth, but if one cannot know the truth, one cannot know what is false either. Knowing what is false is knowledge.
About Certainty
I have no idea what the radical skeptics think certain knowledge is. Certainty does not mean omniscience. It does not mean infallibility. Certainty means knowing what one does know, based on objective evidence within the context of that to which the knowledge pertains. It means one has examined all available evidence and it all supports the knowledge and no evidence exists that contradicts the knowledge. It usually means, when something is known, denying or doubting it contradicts all supporting evidence as well as all related knowledge.
Most knowledge is simple and absolute. The cat is either in the closet or it isn't. Looking in the closet provides absolute knowledge of which it is. This is no doubt what Da Vinci had in mind when he said, "to see is to know."
Everything that ever had to be done that required knowledge to do is proof of of that knowledge. Every blood transfusion ever performed is proof of knowledge about the circulatory system and the nature of blood. Sending men to the moon was proof of the enormous amount of knowledge that was necessary to accomplish that mission. Every trip taken by any human being made possible by any of the man-made means of travel from ships to airplanes is proof of the knowledge necessary to produce those methods of transportation.
There is almost nothing in modern life in Western Civilization that would exist or be possible without heaps of knowledge, from coffee-makers to cell-phones.
Every actual technological achievement is not just probable, it is absolute. We know with absolute certainty that heavier than air human fight is possible, that antibiotics cure many infectious diseases, that the atom can be used to produce usable energy by fission (already done) and fusion (if it can ever be controlled). We know geo-stationary satellites are possible (though it was doubted when Arthur C. Clarke first described it.) We know anesthesia and painless surgery are possible (though the knowledge was fought against when first proposed) Almost everything we do every day would be impossible without the knowledge that made the things we use possible from electricity to air-conditioning.
None of these examples would be possible without certain knowledge. "But human knowledge is always limited, it is never perfectly precise, and nothing can be known to be 100% true," the skeptic says. Human knowledge is limited because human beings are neither omniscient or infallible but that does not mean they have knowledge of nothing or that everything is a mistake. Even when knowledge is limited by the nature of what is known, when absolute precision is impossible, knowledge that a parameter must fall within known limits is in fact certain knowledge. I do not know what, "100% true," means. If a proposition is true, it is true. If it is 99.9999% true, it is then .0001% false, and the proposition itself is false.
One thing is certain, nothing of value has ever been produced and nothing of import has ever been discovered by means of doubt, ignorance, skepticism, or cynicism.

To My Skeptical Friends."
By the way, I'm not trying to convince you of anything or attempting to change your mind. I do not promote any ideology and expect everyone to use their own mind to choose what to believe and how to live their lives, which, unless they overtly harm anyone else, I never judge.
