While leading a weekly group of 100+ riders, descending Mulholland Hwy at nearly 40 MPH a CHP officer pulled up behind us and used his PA to order us out of the roadway. At the time of his request, I was riding on the edge stripe. The shoulder lane was minimal, perhaps, just a couple of feet and in poor condition. The lane width is probably 12 feet. In my opinion, I was riding in the furthest right position on the road in regards to safety. I understand the street was signed for 35 MPH so I was slightly over the speed limit. But realistically speaking I/we were moving at the "normal flow of traffic". Anyway, as we approached another rider I merged left 2 feet to overtake the slower rider. This sent the CHP officer into a road rage. The CHP officer then ordered the entire group to pull to the side of the road.
The group complied and began slowing and moving into the shoulder lane. At this point the officer sped in front of me, abruptly pulled to the right, (now being in front of me) and then applied the brakes extremely hard. (leaving skid marks on the roadway). The group and myself, not expecting such an unpredictable maneuver, wound up running into the back of the officer's car. The injuries to the riders were all minor, cuts/bruises etc. (but who wants to race a 15 lb bike, applying sprinting forces to a machine that has had unengineered forces applied to the forks, handle bars and head tube). Numerous, CHP officers flooded the scene and none of them were willing to pull out their CA VC so I could read 21202 with them and discuss the situation. One officer said, " I don't care about the letter of the law. The spirit of the law says cyclists need to stay out of the way of cars". The SGT on scene said he was too upset by the situation to discuss the matter. But he did claim that we have just seen the end of group bicycle rides in California.
