And yet simple logic dictates Tesla is not going to sell an inferior model (Fremont) vs a superior model (Austin) based simply on where the car is going to get delivered. Anything coming out of Austin will be on par or inferior to what is currently being offered in Fremont, Berlin & Shanghai. One Factory in texas is not all of the sudden overnight going to render Tesla's 3 other manufacturing factories obsolete and worthless because who's going to order those cars if they know they can get something better in Austin.
What Elon said is the eventual goal down the line, but it will take years. Can't retool Fremont/Shanghai/Berlin to do 4680s overnight and those cells are in short supply anyways
