The description most of the drivers give really do make it sound like some sort of computer glitch. Perhaps a spurious signal from a passing cell phone tower or some tv repair guy's two-way radio, a nearby garage door opener. Who knows, but it sure is scary!
It's a perfect scenario for high level corporate sabotage or just a single disgruntled employee. The most difficult thing in the world to pin down in a computer is the irregularly irregular glitch that strikes without warning and then doesn't show up again or a long time.
No it never happened to me, but being in the electronics field I have lately been hearing people who don’t know any better say that something like walkie talkies can cause stuff to do things and cause that sort of thing, it doesn’t work that way. Just think about it, if it was that simple nothing would be viable. RF in every possible frequency is all around us and our stuff works just fine for the most part.
