To the transit driver in the outside lane, after you've looked behind, indicated, then moved into his lane to turn right, giving him plenty of room. you get to the right turn together, and he blasts his horn at you. You ask him what his problem is and he says that you should indicate. you remind him that you did, clearly, and he says that you should also give way. You point out that he was miles back and you didn't cause him to brake any more than he needed to to stop for the right turn. Then he just keeps repeating that you should have given way.
