Per your reply, from TFA:

"Tesla has a habit of rolling out improvements to its vehicles as soon as they are available. The latest Teslas are therefore expected to have the best tech that the company has to offer at the time of their production."

Realizing that Tesla's slipstreaming improvements, completely ignoring model years, was the 3rd or 4th "Oh, this is different." aha moment I've had. And why I think their ridiculous valuation might be semi-rational.

Another aha, per Conways' Law, was learning that Tesla didn't honor the traditional organization structure. Permitting them to create the octovalve and omni heater. (Sorry, I keep forgetting the names given for those parts.)

Right now I can't imagine any other automobile manufacturer shaking their ant farms the same way, allowing organizational blank slate resets. Such is the benefit of no legacy.
