It's not the final design anyway - it can't be, no side mirrors, etc. = not street legal.
The design could change a lot before they're actually selling them. "Production begins late 2021" - so they won't be available until after that, and everything from Tesla gets delayed so... late 2022 before anyone actually has one? Don't hold your breath for the "cheap" one either, they fill all the high-end orders first.
