You go Colleen!
I am not afraid of people that is why I would have no problem confronting a crazed driver. I do it often when I am on my scooter and nearly run off the road. If the driver is stopped at a light or sign, I ride up to them and ask "Are you okay?" Surprised they will look bewildered and I say "Because your driving isn't. You nearly ran me off the road." I then carry on about my business. When they pass by again they say nothing and more than likely have changed lanes.
