As a relative newcomer to Southern California, I should like to make a couple of observations: Nowhere on Earth are people given particular lanes in which "they" make the decisions as to how fast or slow that lane will travel. In Southeast Asia if you want to be in the truck lane (our No. 1, high-speed lane), you better do 100 m.p.h., or the trucks will simply run over you.
In San Francisco and Sacramento, should some motorist decide that his 50 m.p.h. in the No. 1 lane is adequate and traffic starts condensing behind him, he would find himself cited for "obstruction of the flow of traffic." It seems the southern California Highway Patrol officers can't get "Brownie points" for their citations.
Former Gov. Jerry (Moonbeam) Brown's diamond lanes were found to be the cause of so many accidents in Northern California that all have been removed in the interest of public safety.
While I do not condone the use of firearms on the public rights of way, I must admit to a certain desire to, at least occasionally, run into the rear ends of people too busy talking on their phones, but most important never looking in their rear-view mirrors.
