Carpool Lane Purpose Missed

* Re “Diamond Lanes Get Low Grade,” Jan. 9:

I understand the only purpose of diamond lanes is to encourage two drivers of two cars to travel together in one car. Yes?

Then would someone please explain why a driver with one passenger who is a baby, infant or child can use the diamond lane?

Have I missed something? Have I missed noticing all the little lonesome child drivers?
