The real question is why would anyone bother? I have a relative, borderline certifiable IMHO, who at one time firmly believed that she was being actively tracked. It was all I could do to keep from laughing out loud at the suggestion. She, like so many of us, is really a nobody. Go ahead, bug my phone, my house, my car. Warning, I sing (when I'm alone) in the car - badly. Look at any of the so-called reality-based shows polluting the airwaves. TV production companies have to work hard at making "reality" even mildly interesting. Anyone tracking me, I'd probably drive them to drink inside a week.
The upshot is, if someone with enough resources wants to track you, they're going to track you. There's not a heck of a lot you can do about it without living a completely bizarre lifestyle. A little paranoia is good, but this seems to be close-to or over the edge. I refuse to fear my cell phone, car, or anything else. I won't live in a "State of Fear."
