How about the new procedure of checking your cellphone records at the time of a crash to see if you were "distracted"? (I wonder how they know you were talking on it and not a passenger?)
because they can listen to the conversation....
Do you think the internet is truly "free"? I'll bet lotsa people are watching us. I know China can do it with their population. Why can't people do it in the 'free' world? Because we're nicer?
Now, before everyone cubbyholes me as a conspiracy theorist, I'm merely pointing out that technology exists to perform these functions. Whether entities (good or bad) use them (or are using them) is not my point.
