I had one this morning - SS I-drive-a-fast-looking-car-us
I was driving down GA400 this morning, as usual. This is a very heavy traffic road, four lanes in each direction, and a full lane width shoulder on each side - buses can 'skip the line' and drive down these shoulders to avoid traffic legally. Hence, it's neither legal nor a bright idea to drive on the shoulder for any distance at all unless you have a true emergency.
When traffic stopped dead about 3/4 of a mile from my exit, as it typically does, I noticed that a little mini Cooper with racing stripes and a hood scoop intake was behind me, driven by a well dressed woman in her 60s, in a business suit (at least from what I could see) and giant Barbara Bush pearls. Not the sort of person we expect to be an aggressive driver. She was easing into the shoulder, but not all the way, just enough to see around traffic perhaps. She stayed there for the entire distance to the next exit, except when we passed an accident on the shoulder with a police car present, and then roared past me and sped down the exit ramp. I got off, and was right behind her, as she laid on the horn for (I watched the clock) almost 2 full minutes as the guy ahead of her waited for a gap in traffic to make a right on red. She was gesturing wildly the entire time, one finger salute, shaking a fist, just acting insane. She jumped out right behind him in traffic when he turned (nearly cutting off a car) and drove off, well over the speed limit, still honking and gesturing. I last saw her half a block ahead of me, still honking, still shaking her fist, paralleling the guy that had made her wait. I was never so glad to turn off into my office!
