isn't it still faster to just move your hand and rotate the temperature knob than using a voice command "XXXX increase temperature by X degrees"? Using muscle memory feels to me like using the least resources while articulating a phrase utilizes more resources.

I'm sure it is faster to use your hand. But I'm not sure faster is the right metric. Safety is probably higher on my list, and I'd say voice commands are safer than taking your hand off the wheel for any reason.
