How's My Driving?

I was driving on a really busy street at lunch time today and I noticed a white truck a few cars up in front of me that had cut over to the other lane real quick - not something unusual. I tend to keep an eye on cars like this to make sure they are not just aggressive drivers that I need to stay clear of. Well this truck was swerving in and out of traffic and I don't mean your typical changing lanes when you get behind a slow car. This truck was whipping back and forth across 3 lanes of traffic. Twice she slammed on her brakes so hard she had to move over into another lane a little bit to avoid hitting the car in front of her. At one point the truck was behind me right on my bumper, then whipped into the lane on the right and cut right back in front of me so she could pass a car in the other lane and cut right back over there.

Well, she (yes, it was female driver) had one of those "How's my driving?" stickers on the back. After she had whipped out from behind me and then cut back over in front me I had had enough. I grabbed a pen and quickly wrote down the phone number and the number on the truck. I called and reported it. The truck was from an auto parts store. The operator asked for the street I was on, the time, the number of the truck, the sex of the drive and the city and state. She said she will send a report to the drivers supervisor which I am satisfied with, but if I hadn't had Cameron with me, I would have followed that lady right to her store and gone in to complain to the manager. That way I could tell someone exactly what I saw her doing. This lady was just crazy.
