The term "chivalry" originates from medieval knights, who had been operators of devastating war machines of the time. And sure, they were warmongers, sexist, oppressors of working class etc. etc. but there is historical record of honorable behavior. I don't see anything counterintuitive in modern operators of devastating war machines behaving in similar way. Not every warrior is a murderous psychopath. In fact, I have never seen one so they are probably quite rare. While an infantryman, for example, could go through wars for years without ever killing anybody, a pilot is likely to be killing people regularly, just like knights of the past. I imagine the chivalry is the way to cope with killing. People in traffic don't need to develop it because they are not really killing each other (except for rare road rage incidents). On the other hand, samurais, the warrior caste in Japan developed similar behavior, bushido. Likewise, Vedic tradition also speaks of strict warrior code for khatriya, Indian warrior caste.
