You can literally hit the tactile knob on the right of the steering wheel and say, "Turn the heat up to 65" and it will do this. You can say this while keeping your eyes on the road. You can turn up the volume with the left tactile knob on the left side of the steering wheel. The headlights are automatic. Amusingly, you can also say, "My butt is cold" and it will turn on the seat heater in your seat.

Tesla allows you to do all three of the things you stated while keeping your eyes on the road. I can do these things in my Model 3 today.
