Yes, you can do most functions through the voice control. It seems to work pretty well, but I’ve found Siri seems to work better for phone calls vs Tesla’s native voice command.Can a lot of the HVAC/infotainment systems be changed by voice-commands? That's the only thing I don't like about the EV's. Without ever having ridden in one, I don't know much of a nuisance it is to change stuff when it's all on one screen.
