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."
The last thing I’ll say is this: I think it’s unfortunate that you are so invested in defending your position at all costs that you are unable to separate the argument from passive-aggressive personal attacks.
There's your quote, verbatim, and it's false. If you don't want to get called out for verifiably false statements, I'd avoid making them in the future.

Responding to factual inaccuracies is hardly "defending a position at all costs," but I'm sorry if it got you worked up.
