Ok, so I got bored and did what any self-respecting nerd would do. I did an experiment.
I went downstairs and woke my car up. I brought my phone so that I could look at my DNS server logs. And I started issuing voice commands. The verdict? The car attempts to process the command. If it can't, it sends the audio to the mothership.
Commands that are listed in the release notes worked instantly. "Dome lights on", " my feet are cold", " set climate auto" worked without a DNS request, while things it had a harder time with, "Navigate to Xanadu, Virginia" generated api calls to api.mp.tesla.services.
I could be wrong, but a "quick and dirty" experiment seems to indicate that voice recognition occurs on the car.
