Person driving had short hair, like pixie cut. Cannot tell if it's a man or a woman but younger looking. 20-30's years old? There is a sun sticker on the back rear window on the bottom right corner. This person sped onto the right shoulder and then sped over to the fast left lane and then sped back to far right lane where that person had just been in within 5 seconds, crossing through 4 lanes. No regard to people around them or the road.
