You can control AC though the touch screen, which is mostly convenient for the passenger. The driver can also control the AC with a scroll wheel on the steering wheel.
You can control climate through steering wheel controls as well. I can and do control most things - music, temperature, calls, headlights, cruise control - with either voice or using steering wheel controls. Tesla UX is pretty amazing. Compared to that when I’m in my 328i from 2011 it feels outdated.
