This is the most interesting video of the factory I've seen thus far.
This is also the first mention I've encountered of a separate powertrain factory six miles away. When was it completed? Why no videos or details of it? Because that is where the core patent-protected technology comes together?
And those appear to be seriously large brake discs we're seeing, especially given that regenerative braking will handle some of the load. What are their diameters (front and rear)? How much does this car weigh? (Tesla in unusual in having rear brake discs almost as large as the front discs, as the low center of gravity resulting from the heavy battery back under the car results in less nosedive under braking than ICE cars, thus keeping more braking load on the rear wheels.)
