False. There are voice controls, buttons on the steering wheel, the steering wheel itself, pedals, pedestals (for turn signals like other cars), etc. Even autopilot's functionality doesn't require the screen (or touching it).
> music browsing, imperfect automated climate control settings, navigation, insane/ludicrous mode, apps, etc.
None of these things are required to drive the car, and music browsing is controlled by knobs on the steering wheel.
Respectfully there's no way to respond meaningfully when these statements are made in bad faith. You can't walk back your initial claim to "many non-critical non-driving features require using the touchscreen."
