How about you tell me where I am wrong or how they are different . Because I read your wikipedia link and it just seemed to reinforce that it's extremely Googley with Play Store, Voice Assistant and GPS built in to Fords and Volvos. And I found no meaningful differences I didn't already cover. Nor did I on Volvo's page[1]
I'm not going to watch like an hour of youtube videos. I tried scrubbing and didn't see any great UI, although if you want to show me some screenshots I'll look. But it also doesn't matter. I wasn't saying "the UI/UX is bad". I was saying "I don't want any touchscreen UX in my car". I also said "they are uploading my position, speed, car data and microphone data inside the car to Google, as well as letting them control the App Store to my car and thus impose things on all the apps I would want." Although Google may in fact process the audio locally.
