I'd much rather see Sandy jump the line than any celeb. The big downside with celebs getting them early is if any of them have problems there will be a crap load of negative press.
If this is correct it's a 4ah battery, times 48V is less than 200Wh/hrs, that won't be able to do much.

In the Model 3 video he actually says what the rotor coating is: Ferritic Nitrocarburizing, FNC.

Depends on how thick the "surface" coating is. Obviously pads wear faster than rotors by design so there could be a layer on the rotors which lasts many years, and since EV's use the brakes so much less it could last a very long time.
Steering system needs a redundant and isolated power source which still functions if the main pack and 48V system fails since there is no physical connection between the steering wheel and rack. It does not seem to have that which seems like a major fail.
As I mentioned in another thread I'd do a light sanding or wire brush then apply phosphoric acid on the bare metal. It will dissolve the light rust that remains and passivate the surface into iron phosphate and prevent further rusting. Might need to reapply once in a while, or apply some paint...
You don't see it because most vehicles have caps covering the center hub. Most will get surface rust under the caps unless they are painted. If the CT had shipped with caps you'd never notice.
