I recently rented a Ford Focus and the car stereo gets louder when you go faster (to cover up the road noise). It drove us crazy. It was either too loud or you couldn't turn it down enough without turning it off. I spent much more time screwing with the volume then I would have otherwise. Who comes up with these features and why couldn't they have just put a defeat switch on it? Has anyone else come upon this?
