It’s not a full car or even entertainment system, but comma.ai is an opensource autonomous driving software. Last time I looked into this was a few years ago, but basically for most newer cars you can rip out the adaptive cruise control, and effevtively replace it with autonomous driving. Either powered by certain supported phones or dedicated hardware.
If your hate only goes towards touchscreens and not having physical buttons, Mazda is (or at least was) very anti-touchscreen. I haven’t done any research on their current stance or if they have good EVs, but a neighbor of mine was really happy with his Mazda ICE car for having a button for everything.
