That might not be bad, I haven’t researched it. I had heard at some point that all controls were on the giant tablet.

You must not have heard from an actual Tesla owner.

In the most recent update (last week) virtually everything can be done by voice. You can literally say, “my butt is cold” and it will turn on the seat heater. You can say, “turn up the heat” and it will turn up the heat.

The volume and whatnot can be controlled via the tactile roller knobs on the right and left side of the steering wheel.

AC can be controlled by voice as well. Both the temperature and the direction of the vents.

I mean, I think it's more of a party trick honestly. I set the AC vents once when setting up the car and haven't touched it since. I set the temperature once a season, roughly.

It definitely works way better than you would think. It seems like after most people drive one a little bit they are convinced. (I was.)
