I was at an intersection in Emeryville, CA with this guy about a 1/4 mile before this happened. A little ways down the road, I glanced at my speed and saw 40mph in a 30mph zone. He was about 400 feet ahead of me, so he was moving at a pace of around 50-60mph. I had my eye on him the whole time... and saw the very moment a Toyota Prius crossed the intersection without seeing him, and he went full force right into the side of the car. Didn't even have time to apply the brakes.
He did a pretty spectacular cartwheel over the car. Insanely brutal accident, and shocking to see it happen.
Here are the photos, taken seconds after it happened:
