Nope. It's a politeness issue. But it's alright. Own the rudeness. You and the o.p. Own it. I don't know where you ride, but a driver here, no matter how impatient, would never honk at a cyclist waiting to go through an intersection to tell them to move. I can't always move out their way because 50% of the time we are on our commuter tandem, but if I am on a much nimbler single I will squeeze right and wave cars waiting to turn right to go by on my LEFT. Or if there is a left lane I'll get in it and share it with whatever car is already in it. They rarely ever mind. And if they do, what are they going to do about it? The good karma from the right turning cars outweighs the negative energy from the car that now has to share a lane with a lowly bicycle.
