I'd like to know more about the Over the air updates. Can current Tesla owners fill the rest of us in on how they work? Do they just upload randomly, and install randomly? Or is there more to it than that? I know that OTA updates do not require wifi connection to your home, but does it work any better if you do? Do you input your home Wifi password, and it updates at night when you are sleeping? Do you set any type of preferences for this? I'm hopeful that it doesn't randomly update while your driving and at least waits for you to park??? If the install of update is somehow interrupted making it corrupted, can you roll it back, reload it??
