I hear you on the cop magnet thing. The other night I had just turned onto a main road from a stop sign (yes, I made a full stop). A cop goes by me from the other direction, pulls a u-turn and follows me for a mile or so, then pulls another u-turn and leaves. I wasn't even at full speed yet as I had just turned onto the road, let alone speeding.
At least it doesn't sound like you're in any real trouble. It's frustrating, though.
