I don't know, I think looking at passengers while talking is something you do once and then realise that it is stupid.

I did it once, because it seemed natural to look at the person I was talking to, but I immediately felt endangered and have never done it since.

Whereas with the inaccurate portrayal of drowning response, by the time you've realised that what you're doing is wrong somebody is dead.
