I'm told that it is an unpublicized configurable option, otherwise many types of people would be disqualified from being a Tesla customer (think diplomatic, military, et c).

In any case, if it can't be built without GSM tracking, I won't be getting one.

My belief is that Tesla is aiming the for the military and police market who like to have proto-military hardware to jerk off to. So, yeah, seems like they'll have this option.

Or maybe only the military version will have it.

I guess the military/police version will cost multiples of the civilian version too, if I were Musk I'd know I'd want to suck on that "virtually unlimited government budget" tit.
