So what? I've frequently done this, and all I feel is superiority over those who erroneously believe that speed makes right. They have the speed to overtake; let them overtake in the normal manner, as with any other slow driver.
Now, if the circumstances are such as to prevent overtaking for a long distance, which, if it occurs at all, is usually on a road that does not permit 50mph traveling, and if there is a safe place for a cyclist to stop to let the waiting traffic overtake, then I do so. The law says that when five or more vehicles are behind, that stop, where safe, is mandatory, but I will do so with less of a train.
