Teslas occasionally need to reboot / hard reset their software too, when driving no less, and during that period all that information, and most of the controls, are unavailable (like windshield wipers, etc.)
I feel you. I've had my machine blocked for 5 hours as it was pushing an update down my throat. Luckily it gave me a 2 minute warning before the initial reboot so that I could close everything down.
As that was during a client emergency, I had a very happy client that day.
That's not true. You cannot shift gears in the Model X, S, or 3 without the touchscreen - the only way to change into or out of park, drive, or reverse is to swipe on the touchscreen. Only the Model Y has a stalk and it is being removed in the next version.
Also even on older Teslas lights are controlled exclusively via touchscreen.
I don't know what to tell you, you are wrong. I drive a Tesla, I have specifically checked all of what I mentioned when I had this (in my opinion highly problematic) issue happen to me. Have you actually tried it?
As someone who lives in a place where it rains almost every day for 9 months of the year, this reinforces my decision to never buy a Tesla. Does this kill the headlights too?
I had it happen two times this year, but the original comment is wrong, you can use the wipers (and also the headlights) while the touch screen is rebooting.
