Author neglects to consider that carpool lanes could (and should) be converted to "self-driving only", as a phased approach to increasing capacity. Second step

  > Author neglects to consider that carpool lanes could (and should) be converted to "self-driving only", as a phased approach to increasing capacity. That would decrease capacity for the rest of the road. Maybe you could allow single occupant self driven cars to also use the carpool lanes. But to move carpoolers out of the carpool lanes and make them exclusive for self driving cars will simply cause car poolers to stop pooling and will increase traffic.

    Yes, less capacity for manually driven cars because there will be fewer of them. Besides, the capacity increase from a pure self driving lane far outweighs the increase from a carpool lane. In fact, many argue that existing carpool lanes give less overall capacity.
