Those who suggest the motorcycles are out in stronger force because
of the camera are absolutely correct. The guy behind the camera is extremely popular and locals want to get caught on video. I've gone rounds with people about this particular road and how they should take it to the track. I have an acquaintance who has totaled 2 motorcycles on that exact turn and still defends it (even after a motorcycle accident put him in a coma for months).
Is it possible to report this to authorities and have the driver punished even if there is no collisions ? I personally witnessed one incident which a driver intimidated a cyclist riding in front of me by swaying his/her car toward the cyclist direction while riding inside the shoulder. It lasted about 2-3 minutes with the driver driving side by side with the cyclist. It got too dangerous for the cyclist which he had to stop and dismount from his bike, and that was when the car ran away. I guess it started when the rider took 1 lane of the 2 lane road for faster downhill since the shoulder surface was not smooth. eg: bumpy, cracks. It was morning there is only another car.
This kind of stuff always scares me when riding in Socal mountains, which seem to be practice circuit for motorcyclist. Last year I saw motorcyclist almost caused brush fire in Palomar mountain. The guy had accident on downhill that he slide to the side of the road, then the leaked gas from his motorcycle immediately ignited dry leaves around. Fortunately, he and his friends were able to put out the fire.
I would say yes, absolutely. I'll ask a buddy who's an officer in CA before I answer too specifically about their laws.
There is one key phrase that changes things; "I was in fear for my life." My weekend incident absolutely could have been fatal if the driver decided to swerve at me - even if the passenger had made contact with me when trying to swing at me. I believe the same "vehicular assault" type scenario applies as if car v. pedestrian. In my case, I could have pressed charges for the verbal death threats alone.
