I really would like to meet someone from the other 25%. Just out of curiosity to experience a completely different kind of reasoning.
Perhaps they believe the product would be cheaper with abdicating the feature?

Or, perhaps, believe it would get updates? Software in cars tends to grow stale quickly, which is an annoyance if you plan to keep for more than a few years. My eight year old car, for example, has features (had features) that don't work properly anymore because the software didn't anticipate how the rest of the world would change around it and there isn't an update provided to restore it to the original working condition, let alone adding new features that would be nice to have.
And car manufacturers are still very much in a mindset that you make a certain model-year, release it, and then forget about it while you work on the next ones. No upgrade path on software whatsoever.
I've driven in a Tesla with FSD, and it's underwhelming. There's no guarantee that in five years, it will perform significantly better - maybe even require additional hardware or a newer car/platform.
In previous versions "Autopilot" as a name only implied self-driving to some customers, while it wasn't. Now they've gone a step further and branded advanced driver assist as FSD, which really isn't all that self driving at all.
But based on our top-of-line 2019 RAV4 the computerization of the car is way more brittle and pointless than the traditional engineering. I expect to have a collection of dead stuff long before the car dies.
