I was behind the driver. I could see in their rear view mirror that they were looking at their phone more than the road. They had 3 near misses in a half mile. They almost missed a curve in the road and ran head on into traffic going the opposite way. Then we were pulling up to a red light and they were super close to rear ending the person in front of them. They broke hard at the last second. Finally, they almost ran off the road at a right curve in the road.
