Hummer is not supposed to be a luxury car, that is to what the design concept is all about. It is supposed to be boxy, tough, and squarish The problem with large screens that are fully integrated into the dash is that you have to sacrifice the entire dash to make it work, so the choice designers have is smaller screens (not popular with buyers) or stick a big one on the dash which seems to be the current trend. Sounds like you want the upcoming Escalade Ev which will be here in 2023 as a 2024 model and will prioritize luxury / smooth interior design, and will make the URUS interior look like an outdated junker.
