Lordy I hope not. Cannot imagine having to childproof my car's entertainment system, or make sure I don't sing a trigger word, or try to turn on the defroster to dehumidify the windshield during an intense rain storm where I can barely hear myself think.

Also: I don't want a microphone in my car at all times. Thank you.

Hell no. I'd sooner tear out my own vocal cords than accept this future.

No. No, please, no. I won't buy a car that relies on voice for anything, and I really don't want to rent one either. Wildly inefficient, slow, unpredictable.

Voice makes sense as a third input mode, but it seems like a poor replacement for the controls you need while stressed or time-constrained. In a car the real UX test isn't "can the system eventually understand me?", it's "can I do this eyes-free, in noise, with high confidence, in under a second?" That's why defrost, wipers, volume, and temperature feel fundamentally different from "navigate to X". Touch is fine for discoverability, voice is fine for occasional commands, but safety-critical/high-frequency actions still want dedicated hardware.
