Thanks for taking the time to put together that video; and for your steady camera work!
I suspect that silver Roadster is not a fully functional vehicle, even though the lights and screen are powered. If it was functional then I would assume it would have been used for test rides.
It is stunning. The only aspect of the design that I think is a bit off are the lower rear air diffusers. I’m sure they are functional, but the shapes are visually somewhat confusing to me.
