never seen a paceline pulled over and everyone cited to tailgating and I have ridden in hundreds of them.

I really dont care if someone drafts me. If they touch my back wheel, they go down, not me. If someone does draft me, I will point road hazards as a matter of courtesy. It would be good if they took turns pulling but can understand if someone is tired and just needs a break. Not into the resentment and fairness thing. Usually just enjoy the company which makes the miles go by faster. Of course if they are a jerk, I will just stop and let them go by.
