That still might fit, or maybe the feature is not as common as I thought. Certainly it varies by manufacturer , with some being more laggard than others.

My last car I remember not being adjustable was a 1996 Pontiac. It did adjust up-down and was high enough to improve safety rather than risk, but it was too far back and did not adjust front-back so my head would rattle around a lot if there were an accident. I’m pretty sure the Honda, Toyota, and Subaru I had since then all had adjustable headrests. Admittedly I do remember being bothered by something so close until I got used to it, but I knew it was a safety improvement and the front-back adjustment generally allowed me to get it out of the way while minimizing head travel if an accident

As a taller guy, this is something I especially notice: most of my driving life a headrest would simply break my neck if there were an accident. Having it be high enough to act as a safety feature rather than increase risk, was a huge advance, and the more recent adjustment front-back works much better

Yet somehow my Tesla fits best of all despite not adjusting at all: neither up-down nor front-back.

My old car (2007) had adjustable head rests, my current car (2019) does not. Fortunately its not too bad but I would height adjust it an inch or two higher if I could (just like when I get on an airplane). Weirdly, I was battling a really sore neck for a few months and a couple of road trips (1500 miles each way), actually was pretty comfortable. I didn't have to lay down for a couple of hours in the middle of the day.
