CarPlay is irelevant for this use case. You can say Hey Siri/OK Google into the air and just state your request. The phone can connect to the audio system via Bluetooth just like in any other car.
* Press speak button on the steering wheel, speak the query (via car microphone), hear answer via car stereo system with UI response rendered on cars' screen while having the ability to actually control apps on your phone which can then render on car screen.
* Yell at your phone over the car noise and only hear response via audio link and have no ability to control the infotainment system or apps on the phone.
Siri hears me perfectly well in the car without having to yell. The car is rather silent afterall. (Siri is a bad assistant, but that's a separate problem.)
CarPlay would be great but I don't see the relevance to this use case.
What? When you connect your phone to your car over bluetooth it uses the car microphone just like carplay or android auto would use. Why are you yelling at your phone over car noise?
