Discription of Events: Young girl driving car backed up from a parking spot and drove onto a busy street (in reverse)in front of oncoming traffic in both directions. The only thing that kept an accident from happening was my cautious driving but it could have been a nightmare. I have never seen something so incompetent from a driver and I am so thankful no one got hurt. This person should take some serious classes before hitting the road again. It's so sad that she has a license.
