Find out who is picking up and who is dropping off and leave it be.
Most parents that get divorced, have children and live in the same town have to be civil so it shouldn't matter what their custody is on paper because some never do it that way. Some parents are able to get along and just go about living their life with little change except where they are living. 
You have a good point wdmmom. Honestly, most of my confusion about this whole thing was it seemed like nothing ever changed! I'll give what you said some thought.
