In a perfect world, the Owner's Manual would be updated with every new software release. And the bottom layer of every pizza crust would have a little crunch to it, no matter how long it had been sitting.
However, all my other cars only came with one Owner's Manual which was never updated and Tesla has
much bigger things on their menu than just making sure every detail is technically correct for every single software upgrade. In other words, they upgrade the manual when they think the significance of the software upgrade requires a corresponding upgrade to the manual.
Read it and weep all the way back to your next logical replacement car, a Toyota, which only gets worse from the moment you drive it off the lot. But the manual will always be technically correct even though the car keeps getting worse.
