WiFi Off Option

I am a little fearful that Tesla HQ are going to have an Autopilot limitation embedded within the next software update. I would like to decide when, or even if, I want to download that update. If I could disconnect from my home WiFi that would avoid it automatically downloading.

I am not a paranoid person but in this case I agree with Patrick.  Personal privacy is a wide open subject these days and Tesla should either respond with why this is or isn't a good idea.

I will post this comment as a new Desired Feature since it only partially has something to do with WiFi.

I would like to be able to disable ALL radios in the car.... including the 3G card...  this is for privacy or if the Tesla security framework was ever compromised, it would be nice to be able to cut the car off completely from the internet while the problem gets fixed.  The last reason may just because I "want to" be more private in my movements.  As it stands, there's no way for Tesla NOT to know where ever you go in this car, which is a little (ok very) scary having no control over that.

At least on 5.9, the Model S will not connect to a WiFi network unless you configure it to join that specific network.  Perhaps I don't understand the problem here. Model S will not join an open network unless you tell it to join that network.   The only scenario I can think of us that you joined an open network (with no password) with an SSID name "BLAH" once before, and you now visit a location with another open network with SSID name "BLAH," but requires you to log in to a proxy to use it, and you're locked out.  I suggest you tell the Model S to forget using this WiFi SSID. :)
