GM ditching CarPlay could go bad, complain car dealers

This is a most excellent place for technology news and articles.
I suspect that isn't a current restriction, or it may depend on the car model. I have a car from 2018 where I have to plug in my phone for Android Auto work. That car is in the shop right now and I have a new 2023 loaner, and the loaner's Android Auto integration connects directly to my phone via Bluetooth as soon as I start the car. Having experienced both now, I know for sure that wireless Android Auto is gonna be on the list of things I want in my next car.
I have a 2016 Kia Soul (stay away Kia Boyz, it's a push button start!) And have been using this for wireless Android Auto...
