Now you bring up an interesting question. Will a TESLA 3 UI system speak to you in English or the regional language? Will the prompts on the UI also be in that regional language? I hadn't really thought about it because Americans tend to be pretty ethnocentric. I would love my car to speak to me in some foreign language like British English, "By Jove, you've left the bloody bonnet open" or Canadian, "the next Supercharger is 30 kilometers ahead where you can get poutine and a double-double, eh" or Aussie, "SLOW DOWN! or the constable will be on you like a one-legged man in an arse kicking contest!" and let's not forget Spanish. "Caramba cabron, el cargador es muy lejos"
