This is what I've been talking about this entire thread. What people want is a decent infotainment system. Car manufacturers can't seem to accomplish this, and CarPlay is a great solution. CarPlay Ultra goes much beyond this, but consumers aren't actually asking for this, and car manufacturers don't want this either.
There are perhaps a few things that CarPlay Ultra could improve for integration, but it's not really high up on people's wish list. Once you have wireless CarPlay, that's all that people really need and want. I don't think I've ever heard anyone tell me that they'd love to see CarPlay take over the instrument cluster, aside from a few people in this thread.
