01/10/13 (Thursday) at 3:45pm driving West on Cactus Road, between 43rd Ave. & 67th Ave. - this woman has ZERO regard for a speed limit. She is white, in her 40's, longer/straight grayish-tan hair. She drives 20+ over the speed limit and constantly weaves through traffic to get around the law-abiding drivers. Sometimes she uses her signal, sometimes she doesn't - either way, she tends to just cut people off to try and get ahead. Stupid lady kept ending up at the red lights and I would keep catching up to her. I can easily see her causing an accident! BE AWARE!
