But you look people in the eyes when you talk to them. Since Kakashi thought he was immune, it makes far less sense for him to NOT look than it does for him to not look at them.

Even if he was 100% immune, there was nothing to gain from making eye contact; the best case scenario is nothing happens (and he would have been just as well off looking elsewhere). The worst case scenario is what we saw happen.
There was no reason, at that point, for anyone, including the reader, to assume he wasn't immune especially because Kakashi stated it. It was a surprise to everyone.
You're using hindsight to make your conclusions (pun intended). Before that exchange, did you even know that they should not look until Kakashi brought it up? The answer is: no. You did not know, nor did anyone, that looking into the Sharingan would make you more susceptible to a genjutsu. It was Kakashi that revealed that tidbit to us and it was also the same person that revealed having the Sharingan makes one immune.
We then found out a few short moments later that the MS gentjusu techniques are much stronger than the regular genjutsu techs and can overpower even a sharingan having eye.
So here's what you're suggesting: Kakashi awkwardly doesn't look at two people approaching when talking to them for no reason at all. When not observing their person could result in him missing a hand sign or something similar. He has everything to lose by NOT looking at them and everything to gain...based on the knowledge that we all had at the point of confrontation.
In hindsight, we can see that looking at him is bad...but not at that point in time. Nor could Kakashi see that. Your argument is invalid.
"Just look at their feat like Guy did" right? That will be your response in most ways. Why? Now Guy can't see hand signs.
Kakashi would not have been able to copy hand signs if he didn't look up high enough to see them...making his precog fail.
