This will be the first time i have an update available for my MS. I see the alert on my console saying it will take about 1 hour 40 min to install.. couple questions.. 1) is the update already downloaded locally when you get these alerts? I am curious because you can schedule it to install at a certain time since it says you are unable to drive the car during the update. i also ask because when the car is parked in my garage it is connected to wifi and would prefer to have it download the update this way rather then 4G. as of right now since we all have the 3G/4G networks included its not a big deal. but when these big updates are available for cars that no longer have unlimited data i would assume you can have the option to chose whether you'd want to use data or wifi? 2) since Tesla is compared to apple a lot on how things are done.. is there a link or spot where you can see what these new updates are fixing or adding to your software before you update?
