To answer the OP question about enforcement, it is obvious that less and less attention is paid to general enforcement. In our community the LAPD Captain in charge stated publically that he has given his officers instructions not to enforce stop sign violations and other violations by cyclists. It seems that here at least if the bikes slow down traffic, all the better.
I have been a California resident for over 70 years and most drivers understand that the CHP and to a great extent local LEOs do not enforce the motor vehicle code. The CHP does , however, sit in place before most highway construction projects with their engines running, lights flashing and doing nothing but sitting there.
I don't know why anyone would drive 80 miles per hour to get out of a pack of trucks going over the speed limit and then complain drivers were going too fast.
I do cruise at 58 to 60 on CA freeways in my rig and I never have any trucks hassle me. I don't give a Rats whatever about how fast the sprint car drivers go. If they flash their lights or tailgate me in the far right lane for going too slow, the most I do is turn on my flashers for a few seconds to the jerk behind me know that I know he's there and that I'm not going any faster just to make him happy. On two lane roads I try very hard to use pull outs and allow traffic to pass but, there are far to few pull outs that a rig over 5ifty feet long can use safely.
