The car should have been able to get past the cyclist with very little disruption to traffic flow. The driver just didn't appear to move over an inch.
It looks like the handlebars were just barely clipped, sending the rider down.
The clip is cut short, but I'm guessing the cyclist got back up and rode off (car apparently didn't notice and hadn't stopped).
The person getting out of the car is likely the one with the dash cam, and I would think would have mentioned the cam, and the rider just brushed it off.
I doubt we'll see charges, other than "Minimum Passing Distance", and "Leaving the Scene".
For those advising riding in the middle of the lane, one can only hope that a driver that is oblivious to the world around the car would actually see the cyclist.
