> Yes the best way is to use voice control. You can tell the tesla to "set fan speed to 2" and it will do it. Voice commands are the safest imho.

...if you are from English-speaking country or you know English.

Does Tesla understand every language in the world?

Or: how would my father change settings in Tesla? Would he need to learn one English phrase ("Tesla/Alexa/Siri/Whatever, open Google translate"), then speak in his native language, then somehow speak the translated text to Tesla's system?

Currently in his car, he does that by pressing a button. Done.

It does understand Norwegian (even dialect) just fine at least if the car is set to Norwegian UI.
