Side issue. People who are in the carpool lane and going sower than the lanes to the right shouldn’t be in the carpool lane.
One thing I don’t like about Cali’s carpool lanes is that they are “limited access” by double lines. If you happen to be slower than a car behind you, he ends up riding your bumper (and thinking bad thoughts about you and your parents) and you can’t do the decent thing and move to the right and let him go by.
