Given that the (user-facing) software that comes with the car is always broken (modulo Tesla and a few other modern exceptions), it's no wonder people want to replace that software with literally anything else that actually works.

This isn't the auto industry deciding that you need to use your phone. On the contrary, GM and others tried hard to push back on Carplay and AA. This is the buyers telling the auto makers that they want Carplay and AA since they know that that actually works, and they know that the software the car actually comes with will be garbage, or at the very least unfamiliar and not really worth dealing with when you can hook up your phone and let that actually solve the problems the user wants to be solved.

It's insane to me that anyone could be of the opinion that it's good that some automakers ban/don't implement Carplay and AA. It's just taking away user choice. It's hard to believe anyone could have this opinion without either never having driven a modern car, or just being an industry plan.
