I have a feeling that these "answers on the comments" might be cleaned up later since we shouldn't suppose to "answer" on the comment, but I think one of the reasons is that "eye contact" is a more plausible indicator that you are really listening to the speaker, compared to... looking at mouth (still possible as an aid for those with hearing difficulties), looking at hands (I dunno, but may be possible as an aid/visual cue if the hands are active/miming the speech), or looking at body (why???) — Andrew T. 54 secs ago

I have a feeling that these "answers on the comments" might be cleaned up later since we shouldn't suppose to "answer" on the comment, but I think one of the reasons is that the direction of the eyes is usually linked to the attention (just as you said about driving car), and people have a tendency to feel that they are listened if they are both at the same eye-level compared to... looking at mouth (still possible as an aid for those with hearing difficulties), hands (I dunno, but may be possible as an aid/visual cue if the hands are active/miming the speech), body (why???). — Andrew T. 1 min ago
