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.
