It seems that somewhere around 2010, manufacturers changed their seat designs to put the head <thing> much further forwards. I'm not sure why. Every pre-2010 car I've had did not do this. Cars I've had and had this issue with - 2011 5-Series, 2014 Passat, 2017 Range Rover. All post-2010. Post-2010 cars I've had that did not have this issue - 2012 7-Series, but that had the super-duper "comfort" seats where the upper back could be adjusted back & forth and I guess mitigated it.
I sat in a few new BMWs at a show a year or two back and they were all like it. The worst were the M cars with expensive optional carbon bucket seats because the back & head <thing> are in one piece with no adjustment at all. Awful.
I might be an outlier. I'm tall and apparently have superb posture. Maybe I also have a head like a Pterodactyl. We won't go there.

But here's a pic of the RR seat and the shape I need to assume if I'd like my shoulders to be supported.
Who TF has that kind of posture ? Quasimodo. Anyone else ??
It wasn't totally apparent on a 20 minute test drive where you're trying to take in loads of new stuff all at once. With a few 2-hr journeys under my belt it's now bugging me.
