I'm 43 with Duane's and I like to sit with my good eye towards whatever is more interesting.  If I want to look out, then I'd rather my good eye was outward.  If I want to converse inside the car, I'd rather the other way around.  When my husband drives, it is always a bit uncomfortable because he is on my Duane's side and it IS a little hard to talk to him.

As for driving, with my last car I used a special mirror and with my current car I don't.  We with Duane's just need to be extra careful to turn and look in side mirrors before merging. I also always turn my head to look behind me, too.  In over 25 years of driving, I have not had an at-fault moving violation (I had one or two, but other people hit me).  BUT I get a lot of minor dings in my car because it is hard for me to judge distances when parking.

Also, Patrick, your son will probably learn to turn his head, but it is a strain to always do that.  In my opinion, it is considerate, especially when a child is young, for the adults in his or her life to think about where he or she would be the most comfortable and help them out.  For instance, when my son was young and before he had his VRT surgery, neither eye could hit midline so he had no peripheral/lateral vision at all.  He always cried when I went to change his diaper at home, but not at his aunt's house.  Eventually, I figured out that at home, his changing table was such that I approached him from the side and he didn't see me coming and got scared.  At his aunt's I approached from his feet, so he knew what to expect.  When I changed the orientation of his table at home, what do you know, the crying stopped.

And, too, I was aware of my Duane's and an excellent student, but even in high school I never thought to ask my teachers to place me where I would be the most comfortable/have the best vision.  I just accepted where they put me.  In retrospect, I can't believe that and I am certainly going to make sure my son knows that he can ask to be seated where he can see the best.
