I have a different use case. I use voice controls to reply to text messages.

And it has to work with iMessage destinations that are not a phone number. I am unaware of any built-in infotainment system that can handle that. Tesla certainly cannot, as one data point.

Trying to get voice control to work reliably over bluetooth has never been anything but a laggy mess for me. A well implemented CarPlay implementation (even GM...) is way better.
