Interesting post. I can't reply to all of that due to the shear volume, but let me point out something that is notable. The drag coefficient is mentioned as being significant. That is a pro and a con in Tesla cars. Why don't all cars have such low drag coefficients? It's not rocket science, they've designed cars and other objects with low drag coefficients before. Heck, that's even a factor in bullets! It is hard to get such low numbers in cars because it's a trade off. Such low numbers make the cars hard to get in and out of. I've gotten model S cars as loaners several times and I find them very hard to get in and out of. I test drove a model 3 and the same thing. There are times when I hit my head getting into the model X if I don't do it right. This is because the windshield is so raked back that it reduces the roof line over much of the door opening. I literally can't get into the model S without folding rather like a pretzel. Not only do I need to watch my head, but my shoulders because the width of the door opening at the top is a fraction of the width at the bottom.
So while the drag coefficient helps get better range and faster quarter mile times, it makes it harder to sell the cars to middle America. The question is which impacts sales more, the improved performance or the reduced convenience?
