From another article:
WHAT IS BEING INVESTIGATED?
Los Angeles County sheriff’s investigators are trying to determine why the Prius stopped or slowed.
Traffic doesn’t tend to build up on the Pacific Coast Highway in February, and the driver was
150 yards from the next traffic light.
Her statements to investigators were “unclear,” Sgt. Philip Brooks said.
Another big question is why the Lexus veered into oncoming traffic when it was hit by Jenner’s Cadillac.
Usually all three cars stay in line in such an accident. But in this case the Lexus crossed a
12-foot center lane to make its way into the Hummer’s path, Brooks said.

In that report, it said they didn’t have evidence of photographers chasing him. I guess they do now, since someone has close-up pictures of him during the crash.
