Accident took 2 seconds to happen from start to finish. Average reaction time is 1 1/2 sec, but she was already taking action under 1 sec and going for the gap that closed all too quickly...but no one can really account for some moron doing a U-turn on the freeway. Also going around 45 and the car was only 2 car lengths ahead. Probably would have made it if the car on the right did more than just slow down and sandwich her (i.e. it was clear to the right).
