to my knowledge almost everything is touchscreen-only in Telsas (correct me if I'm wrong please!) but in everything else I've seen there's at least physical buttons still for some things.
Controls on the wheel or yoke include: turn signals, horn, windshield wipers, high beams, cruise/autopilot/FSD, voice command, and two 5-way scroll wheel things which are somewhat programmable and enable additional options when another button is pressed. By default I think they control audio, cruise speed, and following distance.
Older models have some of the above on stalks.
Beyond the wheel you've got window controls, gear selector, map lights, buttons and levers to open the doors, a gas and brake pedal, I think that's it
That said, you mostly tell the car what to do with voice commands. "Defrost the windows" or "open the glove box" or "drive to Costco" etc.
