I called Fremont Tesla today to see if I can test-drive Model Y (current EDD of end of Jan'22). somehow my call was re-directly to someone from SoCal. He mentioned that typically you would not find demo vehicle in the store at the beginning of the new Q, especially right after year end Q, like we just had. The new demo vehicle will start to arrive by 2nd or 3rd week. I also asked him if my Model Y will have new 2022 features, especially AMD Ryzen chip. He told me (take this with pinch of salt), "Tesla said all new 2022 vehicles will have AMD Ryzen chip."
I am plan on making a trip to fremont tomorrow (or this week) to see if I can test drive the vehicle. will update if I find out more.
