This may be a bit of a drift-

When I'm doing a long ride, I'll draft with one or two people. Usually because I'm really tired, from wind usually, and they let me hang and take short pulls. But later in the day, they get tired, and I can now take long pulls at a pace they are comfortable with, so it evens out.

I'm happy to have company, whether they can pull or not. It helps the hours go by.
