corollary to the OP is the driver who holds up the car pool lane by traveling slower than the flow of freeway traffic. Here in Socal, one can only enter and exit the carpool lane at designated areas which means you cannot legally pass a slower vehicle until you reach one of the exit/enter areas. There's nothing like getting behind one of those "I'm doing the legal limit" drivers who is holding the entire lane up as cars in the regular lanes consistently pass on the right. I've been in a line of 15-20 cars that all are at the legal mercy of the oblivious/passive-aggressive driver in front. A real PITA.
