We passed a woman who was merging onto the interstate with her left hand on her steering wheel and her head and torso completely turned toward the back seat. I believe she was looking for something in the backseat. There is no way she could see vehicles in front or to the side of her but she was accelerating.
Even as we sped up to get away from her, we could see she was starting to swerve into traffic…still facing her backseat.
