If it will be outdated, how can it be provided at all in a car?
I perceive from the parent comment that there's an assumption that one can just write a low level API that a high level, customizable interface could run against. We aren't far enough along in the process of digital computing in cars to know what that API looks like. So any user interface at all with fancy features requires frontend and backend integration (so that safety testing guarantees can be made if no other reason), and you're there for stuck with either OTA updates, and interface that will look prehistoric within 15 years, or nothing at all.
