Then you will not be buying any cars in your future. You cannot purchase a car without a whole bunch of microprocessors. Data mining is only a side function of these little pieces of equipment. No new model car can operate without them.
Your personal information is being mined by corporations whether you like it or not. That is much more dangerous to you than what NSA has done.
For instance the 60 second pre-crash data may well determine if your claim is honored or not. If it shows you were speeding prior to the crash your insurance claim may be denied. That is just the tip of the iceberg.
You're talking about EDRs. One, they don't "communicate" with anything unless, following a crash, they are subpenaed in Kansas and Missouri by the police. Unless one has Ford's InLine Sync or the old GM (now a free agent) OnStar system, your car doesn't communicate with anyone.
You're an alarmist, CTB. And "more dangerous to you than what NSA has done"? How much did the White House pay you for that one? And even if my truck is in an accident, it won't be my fault, I don't speed, and I haven't had a traffic ticket in 34 years, so I have nothing to fear. No one does if they aren't breaking the law. If EDRs are inevitable, I still won't have to worry about it.
Now, how about you discuss the advisability of the NML having access to your personal medical data through indirect means, which is, after all, the subject of this thread?
