Does Tesla change Model Year designation with the 1st of the next year? For example any Model Y's produced on or after January 1, 2022 will be a Model Year 2022? If not, how will we know when Model Year 2022, Model Y's, are in production or being delivered. I'm not asking for Model Year updates or the new battery pack. Just curious about Model Year designation switch over and how to tell from a consumers perspective.
