Our DLs don’t yet have RFIDs, but you can bet your life I’ll be disabling it by hammer or microwave when they do.
Apps and providers cannot surreptitiously enable GPS on a phone. What I mean by that is that your phone will show that the GPS is on if it’s working. I have an iPhone 4s, and I keep my GPS off. The setting is under Settings > Privacy. I don’t turn it on except for when I need directions somewhere. From everything I read, it’s not possible to turn it on without user knowledge.
E911 is not a two-way function. It’s only activated when you actually dial 911 from your phone.
An automotive black box can be disabled with a very well-placed paper clip. Or just buy a pre-1990 car. I’d prefer a 1972 Chevelle SS 454 myself. One saving grace is that the black box interface is on the inside of the car.
My mistake on the gps. Cell towers can be used to track you. Speaker phone and camera can be remotely activated without it indicating its turned on.
