In the US that is going to restrict you to old used cars. Cars made after 2018 require a backup camera so there is virtually no other way to support the law.
My current car is from 2003 and I'm happy with it. I'm fine with a backup camera screen, as long as I don't need Google/Apple in the mix and the controls (radio, climate, etc.) are not screen-based.
GMC probably doesn’t care about your opinion on what they put in new cars if you’ve conceded you aren’t going to buy one.
But I’d suggest to you that if GMC is not supporting Apple/Android projection it’s not because they want to support something simpler and more open. It’s because they want to own the whole system.
Who do you trust more to build quality software and not rent seek in that situation?
