Also .. . the video shows that the sun was to her right at the stretch of road where the accident happened.
I think what happened is she was passing the cyclists while playing with her phone and drifted out of her lane. The cyclists were probably two abreast, but whatever ... buy the time the driver looked up she had hit the entire line ... at 88 feet per second, she could hit them all in about half a second, which would be about her reaction time.
